Ubuntu Security Notice 6697-1 - It was discovered that Bash incorrectly handled certain memory operations when processing commands. If a user or automated system were tricked into running a specially crafted bash file, a remote attacker could use this issue to cause Bash to crash, resulting in a denial of service, or possibly execute arbitrary code.

f80995082ade857bc8c222749aa3ff2fe683f4b3f02e618e111a589f857646e2An unauthenticated remote code execution vulnerability exists in the embedded webserver in certain Lexmark devices through 2023-02-19. The vulnerability is only exposed if, when setting up the printer or device, the user selects "Set up Later" when asked if they would like to add an Admin user. If no Admin user is created, the endpoint /cgi-bin/fax_change_faxtrace_settings is accessible without authentication. The endpoint allows the user to configure a number of different fax settings. A number of the configurable parameters on the page fail to be sanitized properly before being used in a bash eval statement, allowing for an unauthenticated user to run arbitrary commands.

22c5dc6dfc7500db94b6f8a48775f72b5149d0a372b8552ed7666016ee79edf0This Metasploit module exploits an authenticated command injection vulnerability affecting Cisco ASA-X with FirePOWER Services. This exploit is executed through the ASA's ASDM web server and lands in the FirePower Services SFR module's Linux virtual machine as the root user. Access to the virtual machine allows the attacker to pivot to the inside network, and access the outside network. Also, the SFR virtual machine is running snort on the traffic flowing through the ASA, so the attacker should have access to this diverted traffic as well. This module requires ASDM credentials in order to traverse the ASDM interface. A similar attack can be performed via Cisco CLI (over SSH), although that isn't implemented here. Finally, it's worth noting that this attack bypasses the affects of the lockdown-sensor command (e.g. the virtual machine's bash shell shouldn't be available but this attack makes it available). Cisco assigned this issue CVE-2022-20828. The issue affects all Cisco ASA that support the ASA FirePOWER module (at least Cisco ASA-X with FirePOWER Service, and Cisco ISA 3000). The vulnerability has been patched in ASA FirePOWER module versions 6.2.3.19, 6.4.0.15, 6.6.7, and 7.0.21. The following versions will receive no patch: 6.2.2 and earlier, 6.3.*, 6.5.*, and 6.7.*.

An attacker can craft a malicious ssh agent installation link by URL encoding a bash escape with carriage return line feed. This url encoded payload can be used in place of a token and sent to a user in a social engineering attack. This is fully unauthenticated attack utilizing the trusted teleport server to deliver the payload.

Input passed through the file GET parameter through the logdownload.cgi bash script is not properly verified before being used to download log files. This can be exploited to disclose the contents of arbitrary and sensitive files via directory traversal attacks.

It injects random data into file descriptors of pids associated with a process until the program crashes, then outputs the results of what caused the crash. It leaves behind files that were used as input for the last 2 minutes before the fault, useful for reproduction.

c2beb3ae1fc1301ad845c7aa01c0a292c41b95747ef67f34601f21fb2da16145This archive contains demo exploits for CVE-2022-0185. There are two versions here. The non-kctf version (fuse version) specifically targets Ubuntu with kernel version 5.11.0-44. It does not directly return a root shell, but makes /bin/bash suid, which will lead to trivial privilege escalation. Adjusting the single_start and modprobe_path offsets should allow it to work on most other Ubuntu versions that have kernel version 5.7 or higher; for versions between 5.1 and 5.7, the spray will need to be improved as in the kctf version. The exploitation strategy relies on FUSE and SYSVIPC elastic objects to achieve arbitrary write. The kctf version achieves code execution as the root user in the root namespace, but has at most 50% reliability - it is targeted towards Kubernetes 1.22 (1.22.3-gke.700). This exploitation strategy relies on pipes and SYSVIPC elastic objects to trigger a stack pivot and execute a ROP chain in kernelspace.

cac18b2d6343c61bc55d312a115a6b13a4e02c2b28f3e4b83320cd33353f71a1This Metasploit module exploits an unauthenticated command injection vulnerability within the Nimbus service component of Apache Storm. The getTopologyHistory RPC method method takes a single argument which is the name of a user which is concatenated into a string that is executed by bash. In order for the vulnerability to be exploitable, there must have been at least one topology submitted to the server. The topology may be active or inactive, but at least one must be present. Successful exploitation results in remote code execution as the user running Apache Storm. This vulnerability was patched in versions 2.1.1, 2.2.1 and 1.2.4. This exploit was tested on version 2.2.0 which is affected.
