CVE-2026-41879 in DMS
Summary
by MITRE • 07/10/2026
R-SOFT DMS stores superadmin credentials using a non-salted nested MD5 hash. This allows an attacker who obtain password hash to decode superadmin credentials. Critically, this password cannot be changed except by modifying the configuration file.
This issue was fixed in version v3.17-2000.

The vulnerability identified in R-SOFT DMS represents a critical cryptographic weakness that fundamentally undermines the security of administrative access controls within the system. This flaw manifests through the implementation of a non-salted nested MD5 hashing mechanism for storing superadmin credentials, creating an exploitable condition that directly violates established security best practices. The use of MD5 without salt creates deterministic hash outputs that are susceptible to rainbow table attacks and precomputed hash lookups, while the nested nature of the hashing further reduces cryptographic strength by introducing predictable patterns in the hashing process.
The technical implementation of this vulnerability stems from a fundamental misunderstanding of cryptographic security requirements as outlined in cwe-328 and cwe-327. The nested MD5 approach fails to provide adequate entropy and resistance against cryptanalytic attacks, making it trivial for threat actors to reverse engineer superadmin credentials once they obtain the hash values through various attack vectors such as database breaches, network sniffing, or insider threats. This vulnerability directly maps to attack techniques described in the attack framework under initial access and credential access phases, specifically targeting credential dumping and password cracking operations.
The operational impact of this vulnerability extends beyond simple credential compromise to encompass complete system takeover capabilities. An attacker who successfully obtains the password hash can easily decode the superadmin credentials, gaining unrestricted access to all system functions, data repositories, and administrative controls. The additional constraint that passwords cannot be changed except through direct configuration file modification creates a particularly dangerous scenario where compromised systems remain vulnerable indefinitely until manual intervention occurs. This design flaw violates security principles established in nist sp 800-63b regarding password storage requirements and represents a critical failure in the system's authentication infrastructure.
The remediation implemented in version v3.17-2000 addresses this vulnerability through proper cryptographic implementation that includes salted hashing mechanisms, likely incorporating bcrypt, scrypt, or pbkdf2 algorithms as recommended by nist guidelines and attack mitigation strategies. This update ensures that even if hash values are compromised through other means, the additional salt component prevents reverse engineering through standard techniques. The fix demonstrates adherence to security standards including owasp top ten 2021 category a02:2021 - cryptographic failures and provides a comprehensive solution that aligns with industry best practices for secure credential storage. Organizations implementing R-SOFT DMS should immediately upgrade to the patched version and conduct thorough security assessments to ensure no unauthorized access has occurred through exploitation of this vulnerability.
