CVE-2026-33041 in AVideo
Summary
by MITRE • 03/20/2026
WWBN AVideo is an open source video platform. In versions 25.0 and below, /objects/encryptPass.json.php exposes the application's password hashing algorithm to any unauthenticated user. An attacker can submit arbitrary passwords and receive their hashed equivalents, enabling offline password cracking against leaked database hashes. If an attacker obtains password hashes from the database (via SQL injection, backup exposure, etc.), they can instantly crack them by comparing against pre-computed hashes from this endpoint. This endpoint eliminates the need for an attacker to reverse-engineer the hashing algorithm. Combined with the weak hash chain (md5+whirlpool+sha1, no salt by default), an attacker with access to database hashes can crack passwords extremely quickly. This issue was fixed in version 26.0.

The vulnerability CVE-2026-33041 affects the WWBN AVideo platform, specifically targeting versions 25.0 and earlier. This represents a critical security flaw in the application's authentication mechanism that fundamentally undermines password security. The vulnerability exists within the /objects/encryptPass.json.php endpoint which serves as an unintended backdoor for password hashing information. This endpoint operates without any authentication requirements, making it accessible to any internet user who can reach the platform. The exposure of the password hashing algorithm creates a direct pathway for attackers to perform offline password cracking attacks against compromised database credentials.
The technical implementation of this vulnerability stems from the platform's design flaw where the encryption endpoint returns hashed password values without proper access controls. This endpoint accepts arbitrary password inputs and returns their corresponding hash values, effectively providing attackers with a ready-made tool for password analysis. The vulnerability directly maps to CWE-310, which addresses cryptographic issues in applications, specifically focusing on the exposure of cryptographic functions to unauthorized users. The flaw demonstrates poor security architecture where sensitive cryptographic operations are exposed as public endpoints rather than being properly secured within the application's internal authentication flow.
The operational impact of this vulnerability extends far beyond simple information disclosure. When combined with other security weaknesses in the platform, particularly the weak hash chain implementation using md5+whirlpool+sha1 without salt, the vulnerability becomes extremely dangerous. This weak cryptographic approach, classified under CWE-327, creates an environment where password cracking becomes trivially easy. The lack of salt means that identical passwords produce identical hash outputs, enabling attackers to use pre-computed rainbow tables and hash databases for rapid password recovery. Attackers can leverage this endpoint to collect hash values from database breaches and immediately perform offline cracking attacks without the need for time-consuming reverse engineering processes.
The security implications of this vulnerability align with several ATT&CK techniques including T1566 for credential access through exploitation of weak cryptographic implementations and T1588 for the development of capabilities that leverage system weaknesses. The vulnerability essentially creates a perfect storm for credential compromise where attackers can bypass traditional authentication mechanisms and directly target password hashes with minimal effort. The fix implemented in version 26.0 demonstrates proper remediation through access control enforcement and cryptographic security improvements. Organizations using affected versions should immediately implement access controls to prevent unauthorized access to the encryption endpoint while also migrating to stronger hashing algorithms that incorporate proper salting mechanisms.
The vulnerability highlights critical gaps in the platform's security posture and serves as a reminder of the importance of proper authentication design and cryptographic implementation. The exposure of password hashing algorithms represents a fundamental flaw in security architecture that can be exploited across multiple attack vectors. This vulnerability demonstrates how seemingly minor implementation details can create catastrophic security consequences, particularly when combined with weak cryptographic practices. The remediation approach should focus not only on securing the specific endpoint but also on implementing comprehensive cryptographic security measures including proper hash salting, stronger hashing algorithms, and robust access control mechanisms to prevent similar vulnerabilities from emerging in other parts of the application.
