CVE-2023-24805: Command injection in cups-filters

HighCVSS 8.8 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 36/100)

The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
Probability of exploitation in the next 30 days: 3.6% (FIRST EPSS); higher than 89.8% of all records.
Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
Fixed version: cups-filters (AlmaLinux:8) 1.20.0-29.el8_8.2; cups-filters-devel (AlmaLinux:8) 1.20.0-29.el8_8.2; cups-filters-libs (AlmaLinux:8) 1.20.0-29.el8_8.2.

Low priority for now. Upgrade to cups-filters (AlmaLinux:8) 1.20.0-29.el8_8.2; cups-filters-devel (AlmaLinux:8) 1.20.0-29.el8_8.2; cups-filters-libs (AlmaLinux:8) 1.20.0-29.el8_8.2 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

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.
