18 April 2019: ManageEngine Applications Manager 14 SQL Injection / Remote Code Execution - Files ≈ Packet Storm This Metasploit module exploits SQL injection and command injection vulnerabilities in ManageEngine AM 14 and prior versions. An unauthenticated user can gain the authority of "system" on the server due to the SQL injection vulnerability. The exploit allows the writing of the desired file to the system using the postgresql structure. The module is written over the payload by selecting a file with the extension ".vbs" that is used for monitoring by the ManageEngine which working with "system" authority. In addition, it dumps the users and passwords from the database for us. After the harmful ".vbs" file is written, the shell session may be a bit late.
Fri, 19 Apr 2019 17:53:48 +0000: VU#730261: Marvell Avastar wireless SoCs have multiple vulnerabilities - CERT Recently Published Vulnerability Notes A presentation at the ZeroNights 2018 conference describes multiple security issues with Marvell Avastar SoCs(models 88W8787,88W8797,88W8801,88W8897,and 88W8997). The presentation provides some detail about a block pool memory overflow. During Wi-Fi network scans,an overflow condition can be triggered,overwriting certain block pool data structures. Because many devices conduct automatic background network scans,this vulnerability could be exploited regardless of whether the target is connected to a Wi-Fi network and without user interaction.
Fri, 19 Apr 2019 17:32:53 +0000: VU#166939: Broadcom WiFi chipset drivers contain multiple vulnerabilities - CERT Recently Published Vulnerability Notes Vulnerabilities in the open source brcmfmac driver: CVE-2019-9503:If the brcmfmac driver receives a firmware event frame from a remote source,the is_wlc_event_frame function will cause this frame to be discarded and not be processed. If the driver receives the firmware event frame from the host,the appropriate handler is called. This frame validation can be bypassed if the bus used is USB(for instance by a wifi dongle.). This can allow firmware event frames from a remote source to be processed. CVE-2019-9500:If the Wake-up on Wireless LAN functionality is configured,a malicious event frame can be constructed to trigger an heap buffer overflow in the brcmf_wowl_nd_results function. This vulnerability can be exploited by compromised chipsets to compromise the host,or when used in combination with the above frame validation bypass,can be used remotely. NOTE:The brcmfmac driver only works with Broadcom FullMAC chipsets. Vulnerabilities in the Broadcom wl driver: Two heap buffer overflows can be triggered in the client when parsing an EAPOL message 3 during the 4-way handshake from the access point(AP). CVE-2019-9501:By supplying a vendor information element with a data length larger than 32 bytes,a heap buffer overflow is triggered in wlc_wpa_sup_eapol. CVE-2019-9502:If the vendor information element data length is larger than 164 bytes,a heap buffer overflow is triggered in wlc_wpa_plumb_gtk. NOTE:When the wl driver is used with SoftMAC chipsets,these vulnerabilities are triggered in the host's kernel. When a FullMAC chipset is being used,these vulnerabilities would be triggered in the chipset's firmware.

Tue, 16 Apr 2019 11:28:04 +0000: VU#871675: WPA3 design issues and implementation vulnerabilities in hostapd and wpa_supplicant - CERT Recently Published Vulnerability Notes CERT continues to review the WPA3 protocol in support of this body of research. The root cause of the numerous"implementation"vulnerabilities may involve modifying the protocol. WPA3 uses Simultaneous Authentication of Equals(SAE),also known as Dragonfly Key Exchange,as the initial key exchange protocol,replacing WPA2's Pre-Shared Key(PSK)protocol. hostapd is a daemon for access point and authentication servers used by WPA3 authentication. wpa_supplicant is a wireless supplicant that implements key negotiation with the WPA Authenticator and supports WPA3. Both of these components,as implemented with Extensible Authentication Protocol Password(EAP-PWD)and SAE,are vulnerable as follows: CVE-2019-9494:SAE cache attack against ECC groups(SAE side-channel attacks)- CWE-208 and CWE-524 The implementations of SAE in hostapd and wpa_supplicant are vulnerable to side channel attacks as a result of observable timing differences and cache access patterns. CVE-2019-9495:EAP-PWD cache attack against ECC groups(EAP-PWD side-channel attack)- CWE-524 The implementations of EAP-PWD in hostapd and wpa_supplicant are vulnerable to side channel attacks as a result of cache access patterns. Versions of hostapd and wpa_supplicant versions 2.7 and earlier,with EAP-PWD support are vulnerable. CVE-2019-9496:SAE confirm missing state validation - CWE-642 An invalid authentication sequence could result in the hostapd process terminating due to missing state validation steps when processing the SAE confirm message when in hostapd/AP mode. All version of hostapd with SAE support are vulnerable. CVE-2019-9497:EAP-PWD reflection attack(EAP-PWD missing commit validation)- CWE-301 The implementations of EAP-PWD in hostapd EAP Server and wpa_supplicant EAP Peer do not validate the scalar and element values in EAP-pwd-Commit. CVE-2019-9498:EAP-PWD server missing commit validation for scalar/element - CWE-346 The implementations of EAP-PWD in hostapd EAP Server,when built against a crypto library missing explicit validation on imported elements,do not validate the scalar and element values in EAP-pwd-Commit. CVE-2019-9499:EAP-PWD peer missing commit validation for scalar/element - CWE-346 The implementations of EAP-PWD in wpa_supplicant EAP Peer,when built against a crypto library missing explicit validation on imported elements,do not validate the scalar and element values in EAP-pwd-Commit.

MyCar add smartphone-controlled geolocation,remote start/stop and lock/unlock capabilities to a vehicle with a compatible remote start unit. The MyCar Controls mobile application contains hard-coded admin credentials(CWE-798)which can be used in place of a user's username and password to communicate with the server endpoint for a target user's account. This vulnerability affects versions prior to 3.4.24 on iOS and prior to 4.1.2 on Android.
Wed, 20 Feb 2019 21:06:58 +0000: VU#465632: Microsoft Exchange server 2013 and newer are vulnerable to NTLM relay attacks - CERT Recently Published Vulnerability Notes Microsoft Exchange supports a API called Exchange Web Services(EWS). One of the EWS API functions is called PushSubscriptionRequest,which can be used to cause the Exchange server to connect to an arbitrary website. Connections made using the PushSubscriptionRequest function will attempt to negotiate with the arbitrary web server using NTLM authentication. Starting with Microsoft Exchange 2013,the NTLM authentication over HTTP fails to set the NTLM Sign and Seal flags. The lack of signing makes this authentication attempt vulnerable to NTLM relay attacks. Microsoft Exchange is by default configured with extensive privileges with respect to the Domain object in Active Directory. Because the Exchange Windows Permissions group has WriteDacl access to the Domain object,this means that the Exchange server privileges obtained using this vulnerability can be used to gain Domain Admin privileges for the domain that contains the vulnerable Exchange server.
Mon, 04 Feb 2019 19:46:49 +0000: VU#395981: Self-encrypting hard drives do not adequately protect data - CERT Recently Published Vulnerability Notes CVE-2018-12037 There is no cryptographic relation between the password provided by the end user and the key used for the encryption of user data. This can allow an attacker to access the key without knowing the password provided by the end user,allowing the attacker to decrypt information encrypted with that key. According to National Cyber Security Centre - The Netherlands(NCSC-NL),the following products are affected by CVE-2018-12037: Crucial(Micron)MX100,MX200 and MX300 drives Samsung T3 and T5 portable drives Samsung 840 EVO and 850 EVO drives(In"ATA high" mode these devices are vulnerable,In"TCG"or"ATA max"mode these devices are NOT vulnerable.) CVE-2018-12038 Key information is stored within a wear-leveled storage chip. Wear-leveling does not guarantee that an old copy of updated data is fully removed. If the updated data is written to a new segment,old versions of data may exist in the previous segment for some time after it has been updated(until that previous segment is overwritten). This means that if a key is updated with a new password,the previous version of the key(either unprotected,or with an old password)could be accessible,negating the need to know the updated password. According to NCSC-NL,the following products are affected by CVE-2018-12038: Samsung 840 EVO drives Other products were not reported to have been tested,and similar vulnerabilities may be found in those products.
Tue, 15 Jan 2019 16:31:36 +0000: VU#741315: Dokan file system driver contains a stack-based buffer overflow - CERT Recently Published Vulnerability Notes CWE-121:Stack-based Buffer Overflow - CVE-2018-5410 Dokan,versions between 184.108.40.20600 and 220.127.116.110,are vulnerable to a stack-based buffer overflow in the dokan1.sys driver.

Mon, 07 Jan 2019 19:17:29 +0000: VU#317277: Texas Instruments CC2640 and CC2650 microcontrollers vulnerable to heap overflow and insecure update - CERT Recently Published Vulnerability Notes CWE-119:Improper Restriction of Operations within the Bounds of a Memory Buffer CVE-2018-16986 - also known as BLEEDINGBIT The following Texas Instrument chips are affected: CC2640(non-R2)with BLE-STACK version 2.2.1 or an earlier version CC2650 with BLE-STACK version 2.2.1 or an earlier version CC2640R2F with SimpleLink CC2640R2 SDK version 1.00.00.22(BLE-STACK 3.0.0)CC1350 with SimpleLink CC13x0 SDK version 2.20.00.38(BLE-STACK 2.3.3)or an earlier version The above Texas Instruments controllers contain BLE-Stacks with a memory corruption vulnerability resulting from the mishandling of BLE advertising packets. The function llGetAdvChanPDU that is part of the embedded ROM image in both chips handles the incoming advertising packets and parses their headers. It copies the contents to a separate buffer provided by the calling function. The incorrect length of the packet is taken and ends up being parsed as larger packets than originally intended. If the incoming data is over a certain length,the function will call the halAssertHandler function,as defined by the application running on top of the stack,and not stop execution. Since the flow of execution does not stop,it will copy the overly large packet to the buffer and cause a heap overflow. CVE-2018-7080 - also known as BLEEDINGBIT The following Texas Instruments devices are affected if the Over the Air firmware Download(OAD)feature is enabled and not sufficiently secured: CC2642R CC2640R2 CC2640 CC2650 CC2540 CC2541 Certain Aruba access points are affected. The OAD feature allows for remote firmware updates of some BLE chips. An attacker could connect to a BLE chip on a vulnerable access point(either without authentication or by obtaining the password through other means depending on the implementation)and upload their own malicious firmware,which could give them complete control over the access point.
