CVE-2024-47176: cups-browsed binds to `INADDR_ANY:631`, trusting any packet from any source

Noroxi assessment

Priority: This week (action score 60/100)

  • A ready-made attack module is public (Metasploit, Nuclei); exploiting it takes no special expertise.
  • A ready-made attack tool exists and the flaw can be exploited over the network without an account, so priority is at least “This week”.
  • Probability of exploitation in the next 30 days: 50.6% (FIRST EPSS); higher than 98.9% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: cups-filters (AlmaLinux:8) 1.20.0-35.el8_10; cups-filters-devel (AlmaLinux:8) 1.20.0-35.el8_10; cups-filters-libs (AlmaLinux:8) 1.20.0-35.el8_10.

Don’t wait for the next maintenance window. Upgrade to cups-filters (AlmaLinux:8) 1.20.0-35.el8_10; cups-filters-devel (AlmaLinux:8) 1.20.0-35.el8_10; cups-filters-libs (AlmaLinux:8) 1.20.0-35.el8_10 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

CUPS is a standards-based, open-source printing system, and `cups-browsed` contains network printing functionality including, but not limited to, auto-discovering print services and shared printers. `cups-browsed` binds to `INADDR_ANY:631`, causing it to trust any packet from any source, and can cause the `Get-Printer-Attributes` IPP request to an attacker controlled URL. When combined with other vulnerabilities, such as CVE-2024-47076, CVE-2024-47175, and CVE-2024-47177, an attacker can execute arbitrary commands remotely on the target machine without authentication when a malicious printer is printed to.
