Noroxi assessment
Priority: Monitor (action score 30/100)
- 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: 9.7% (FIRST EPSS); higher than 95.6% of all records.
- Fixed version: nginx (Debian:12) 1.1.19-1; nginx (openSUSE:Tumbleweed) 1.11.4-2.5.
- Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).
Low priority for now. Upgrade to nginx (Debian:12) 1.1.19-1; nginx (openSUSE:Tumbleweed) 1.11.4-2.5 or later.

Primary sources: NVD · CVE.org · FIRST EPSS
Buffer overflow in ngx_http_mp4_module.c in the ngx_http_mp4_module module in nginx 1.0.7 through 1.0.14 and 1.1.3 through 1.1.18, when the mp4 directive is used, allows remote attackers to cause a denial of service (memory overwrite) or possibly execute arbitrary code via a crafted MP4 file.

Weakness class (CWE)
CWE-120 · Buffer Copy without Checking Size of Input ('Classic Buffer Overflow')CVSS vector
AV:N/AC:M/Au:N/C:P/I:P/A:P

Root cause
When data is copied, the source length is not compared with the size of the destination buffer. Excess data overwrites adjacent memory.
