CVE-2023-35964· NVD / CVE Program· CNA talos

Multiple OS command injection vulnerabilities exist in the decompression functionality of GTKWave 3.3.115.

Noroxi assessment

Priority: Monitor (action score 31/100)

  • 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 73.2% 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.
  • Fixed version: gtkwave (Debian:10) 3.3.98+really3.3.118-0+deb10u1; gtkwave (Debian:11) 3.3.104+really3.3.118-0+deb11u1; gtkwave (Debian:12) 3.3.118-0.1~deb12u1.

Low priority for now. Upgrade to gtkwave (Debian:10) 3.3.98+really3.3.118-0+deb10u1; gtkwave (Debian:11) 3.3.104+really3.3.118-0+deb11u1; gtkwave (Debian:12) 3.3.118-0.1~deb12u1 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Multiple OS command injection vulnerabilities exist in the decompression functionality of GTKWave 3.3.115. A specially crafted wave file can lead to arbitrary command execution. A victim would need to open a malicious file to trigger these vulnerabilities.This vulnerability concerns decompression in the `vcd2lxt` utility.
