What is CVE-2025-33027?
CVE-2025-33027 is a medium-severity vulnerability in Bandisoft Bandizip, published on 15 Apr 2025. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Official description
In Bandisoft Bandizip through 7.37, there is a Mark-of-the-Web Bypass Vulnerability. This vulnerability allows attackers to bypass the Mark-of-the-Web protection mechanism on affected installations of Bandizip. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the handling of archived files. When extracting files from a crafted archive that bears the Mark-of-the-Web, Bandizip does not propagate the Mark-of-the-Web to the extracted files. An attacker can leverage this vulnerability to execute arbitrary code in the context of the current user. NOTE: this is disputed because Mark-of-the-Web propagation can increase risk via security-warning habituation, and because the intended control sphere for file-origin metadata (e.g., HostUrl in Zone.Identifier) may be narrower than that for reading the file's content.
