CVE-2023-29246: Apache OpenMeetings: allows null-byte Injection
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 73.6% of all records.
- Anyone who can reach it over the internet can trigger it. Administrator privileges are required. No user action is required. No special conditions are required; it is repeatable.
- Fixed version: Apache Software Foundation Apache OpenMeetings 7.1.0.
Low priority for now. Upgrade to Apache Software Foundation Apache OpenMeetings 7.1.0 or later.
