CVE-2023-42875: Processing web content may lead to arbitrary code execution.

Noroxi assessment

Priority: Monitor (action score 29/100)

  • 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: 0.55% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • Fixed version: webkit2gtk (Debian:11) 2.42.1-1~deb11u1; webkit2gtk (Debian:12) 2.42.1-1~deb12u1; webkit2gtk (Debian:13) 2.42.0-1.

Low priority for now. Upgrade to webkit2gtk (Debian:11) 2.42.1-1~deb11u1; webkit2gtk (Debian:12) 2.42.1-1~deb12u1; webkit2gtk (Debian:13) 2.42.0-1 or later.
