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.
This vulnerability carries a MEDIUM severity rating with a CVSS v3.1 score of 4.3, indicating it can be exploited remotely over the network with relatively low complexity though user interaction is required and does not require pre-existing privileges . The vulnerability impacts limited integrity, for affected systems. Impacting 1 product from rarlab organizations running these solutions should prioritize assessment and patching.
Reported in 2024, this vulnerability emerged during an era marked by increased sophistication in supply chain attacks, cloud infrastructure vulnerabilities, and software-as-a-service (SaaS) security challenges. Security practices during this period emphasized zero-trust architectures, container security, and API protection.

SecUtils normalizes and enriches National Vulnerability Database (NVD) records by standardizing vendor and product identifiers, aggregating vulnerability metadata from both NVD and MITRE sources, and providing structured context for security teams. For rarlab's affected products, we extract Common Platform Enumeration (CPE) data, Common Weakness Enumeration (CWE) classifications, CVSS severity metrics, and reference data to enable rapid vulnerability prioritization and asset correlation. This record contains no exploit code, proof-of-concept instructions, or attack methodologies—only defensive intelligence necessary for patch management, risk assessment, and security operations.
