HighCVSS 7.5 · v2.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 32/100)

  • 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: 5.5% (FIRST EPSS); higher than 92.9% of all records.
  • No special conditions are required; it is repeatable.
  • Fixed version: syslog-ng (Debian:12) 1.5.21-1; syslog-ng (Debian:3.0) 1.5.15-1.1.

Low priority for now. Upgrade to syslog-ng (Debian:12) 1.5.21-1; syslog-ng (Debian:3.0) 1.5.15-1.1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Balabit Syslog-NG 1.4.x before 1.4.15, and 1.5.x before 1.5.20, when using template filenames or output, does not properly track the size of a buffer when constant characters are encountered during macro expansion, which allows remote attackers to cause a denial of service and possibly execute arbitrary code.
