DescriptionNVD

cups-filters contains backends, filters, and other software required to get the cups printing service working on operating systems other than macos. If you use the Backend Error Handler (beh) to create an accessible network printer, this security vulnerability can cause remote code execution. beh.c contains the line retval = system(cmdline) >> 8; which calls the system command with the operand cmdline. cmdline contains multiple user controlled, unsanitized values. As a result an attacker with network access to the hosted print server can exploit this vulnerability to inject system commands which are executed in the context of the running server. This issue has been addressed in commit 8f2740357 and is expected to be bundled in the next release. Users are advised to upgrade when possible and to restrict access to network printers in the meantime.

AnalysisAI

cups-filters contains backends, filters, and other software required to get the cups printing service working on operating systems other than macos. Rated high severity (CVSS 8.8), this vulnerability is remotely exploitable, low attack complexity. Public exploit code available.

Technical ContextAI

This vulnerability is classified as OS Command Injection (CWE-78), which allows attackers to execute arbitrary operating system commands on the host. cups-filters contains backends, filters, and other software required to get the cups printing service working on operating systems other than macos. If you use the Backend Error Handler (beh) to create an accessible network printer, this security vulnerability can cause remote code execution. beh.c contains the line retval = system(cmdline) >> 8; which calls the system command with the operand cmdline. cmdline contains multiple user controlled, unsanitized values. As a result an attacker with network access to the hosted print server can exploit this vulnerability to inject system commands which are executed in the context of the running server. This issue has been addressed in commit 8f2740357 and is expected to be bundled in the next release. Users are advised to upgrade when possible and to restrict access to network printers in the meantime. Affected products include: Linuxfoundation Cups-Filters, Fedoraproject Fedora, Debian Debian Linux.

RemediationAI

A vendor patch is available. Apply the latest security update as soon as possible. Avoid passing user input to shell commands. Use language-specific APIs instead of shell execution. Apply strict input validation with allowlists.
