CVE-2025-33028

Status: DeferredMedium (6.1)—

In WinZip through 29.0, there is a Mark-of-the-Web Bypass Vulnerability because of an incomplete fix for CVE-2024-8811. This vulnerability allows attackers to bypass the Mark-of-the-Web protection mechanism on affected installations of WinZip. 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, WinZip 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: a third party has reported that this is a false positive, and has observed that the original CVE-2025-33028.md file has been deleted on GitHub. Also, 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.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

      "value": "En WinZip hasta la versión 29.0, existe una vulnerabilidad de omisión de la marca de la web debido a una corrección incompleta para CVE-2024-8811. Esta vulnerabilidad permite a los atacantes eludir el mecanismo de protección de la marca de la web en las instalaciones afectadas de WinZip. Para explotar esta vulnerabilidad, se requiere la interacción del usuario, ya que el objetivo debe visitar una página maliciosa o abrir un archivo malicioso. La falla específica se encuentra en la gestión de archivos comprimidos. Al extraer archivos de un archivo comprimido manipulado con la marca de la web, WinZip no la propaga a los archivos extraídos. Un atacante puede aprovechar esta vulnerabilidad para ejecutar código arbitrario en el contexto del usuario actual."
