Noroxi assessment

Priority: Monitor (action score 15/100)

  • 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: 1.9% (FIRST EPSS); higher than 80.3% 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. Special conditions such as timing or configuration are required.
  • Fixed version: cgit (Debian:12) 0.11.2.git2.3.2-1.1; cgit (Debian:8) 0.10.2.git2.0.1-3+deb8u1; cgit (openSUSE:Tumbleweed) 1.0-1.3.

Low priority for now. Upgrade to cgit (Debian:12) 0.11.2.git2.3.2-1.1; cgit (Debian:8) 0.10.2.git2.0.1-3+deb8u1; cgit (openSUSE:Tumbleweed) 1.0-1.3 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

CRLF injection vulnerability in the cgit_print_http_headers function in ui-shared.c in CGit before 0.12 allows remote attackers with permission to write to a repository to inject arbitrary HTTP headers and conduct HTTP response splitting attacks or cross-site scripting (XSS) attacks via newline characters in a filename.
