CVE-2026-57310 in Windu CMS
Summary
by MITRE • 07/20/2026
Windu CMS uses hashing algorithm based on MD5 and SHA1 with static salt to store user passwords. This allows an attacker who obtain password hash to decode user credentials.
Because vendor contact attempts were unsuccessful, the vulnerability has only been confirmed in version 4.1 but may also affect other versions.

Windu CMS implements a fundamentally flawed password storage mechanism that relies on outdated cryptographic hashing algorithms combined with static salt values. This vulnerability represents a critical security weakness that directly violates established cybersecurity best practices and industry standards. The use of MD5 and SHA1 algorithms for password hashing exposes the system to numerous well-documented attack vectors including rainbow table attacks, brute force operations, and collision exploits that have been extensively researched and documented within the cybersecurity community.
The technical flaw stems from the combination of weak cryptographic primitives with predictable static salt values that eliminate the entropy necessary to protect user credentials. MD5 and SHA1 are both deprecated hashing algorithms that have known vulnerabilities and are no longer considered secure for password storage purposes according to nist guidelines and owasp recommendations. The implementation of static salt values further compounds the vulnerability by providing attackers with consistent attack surfaces that can be pre-computed and exploited across multiple user accounts simultaneously.
From an operational impact perspective, this vulnerability creates an immediate and severe risk to all user accounts within the Windu CMS system. Attackers who gain access to password hash files can leverage the weakness to recover plaintext credentials through various methods including pre-computed rainbow tables, specialized brute force tools, or custom attack scripts that exploit the predictable nature of the hashing implementation. The vulnerability affects the confidentiality and integrity of user authentication data, potentially enabling unauthorized access to administrative functions and sensitive system resources.
The security implications extend beyond simple credential compromise as this weakness violates multiple cybersecurity standards including cwe-327 which specifically addresses weak cryptographic algorithms and cwe-310 which covers insufficient entropy in cryptographic operations. Organizations utilizing Windu CMS version 4.1 and potentially other versions face significant risk of data breaches, unauthorized system access, and potential lateral movement within their network infrastructure. The vulnerability also aligns with attack patterns documented in the mitre att&ck framework under credential access tactics where adversaries seek to obtain valid credentials through various exploitation techniques.
Recommended mitigations include immediate implementation of strong password hashing algorithms such as bcrypt, scrypt, or argon2 with unique salt values for each password. System administrators should also implement additional security controls including multi-factor authentication, account lockout mechanisms, and regular security auditing procedures. The vendor should be contacted to provide a patched version addressing this vulnerability, though given the history of unsuccessful contact attempts, organizations may need to consider alternative solutions or migration to more secure content management platforms that adhere to current cryptographic standards and security best practices established by industry frameworks including nist, owasp, and iso/iec 27001.
