CVE-2024-30370: RARLAB WinRAR Mark-Of-The-Web Bypass Vulnerability
Noroxi assessment
Priority: Monitor (action score 17/100)
- 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: 1.1% (FIRST EPSS); higher than 67.2% of all records.
- Anyone who can reach it over the internet 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.
Low priority for now. Update when a fix is released; follow the vendor's advisory.

RARLAB WinRAR Mark-Of-The-Web Bypass Vulnerability. This vulnerability allows remote attackers to bypass the Mark-Of-The-Web protection mechanism on affected installations of RARLAB WinRAR. User interaction is required to exploit this vulnerability in that the target must perform a specific action on a malicious page. The specific flaw exists within the archive extraction functionality. A crafted archive entry can cause the creation of an arbitrary file without the Mark-Of-The-Web. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the current user. Was ZDI-CAN-23156.
