HighCVSS 7.1 · v3.1—No exploit No fix recorded

Noroxi assessment

Priority: Monitor (action score 28/100)

  • 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: 1.4% (FIRST EPSS); higher than 73.5% of all records.
  • Someone with local access to the system can trigger it. No account or password is required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • According to the record, no fixed version is available yet.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Update when a fix is released; follow the vendor's advisory.

Primary sources: NVD · CVE.org · FIRST EPSS

Drawings SDK (All versions prior to 2022.4) are vulnerable to an out-of-bounds read due to parsing of DWG files resulting from the lack of proper validation of user-supplied data. This can result in a read past the end of an allocated buffer and allows attackers to cause a denial-of service condition or read sensitive information from memory.
