Summary

CVE-2026-41879 is a high-severity Use of Weak Hash (CWE-328) vulnerability in Cert (inferred from references). Its CVSS base score is 8.2 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique OS Credential Dumping (T1003); ranked at the 10th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SC-13 (Cryptographic Protection) — see the control section below for these in your framework.

Vulnerability Data

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…

Mitigating Controls (NIST 800-53 r5) AI

SC-13 Cryptographic Protection good match

Mandating approved cryptographic algorithms and strengths directly stops selection of weak hash functions for integrity or other uses.

Mitigating Controls (NIST CSF 2.0) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.PS-06 full match
prevents

Secure-SDLC requirements explicitly forbid weak cryptographic algorithms, fully preventing CWE-328 while covering only one aspect of development practice.

PR.DS-01 mostly match
prevents

Proper data-at-rest integrity protection requires strong cryptographic hashes, directly blocking weak-hash usage.

PR.DS-02 mostly match
prevents

Data-in-transit integrity likewise depends on strong hashes, so the control prevents the weakness while the weakness only partially satisfies the outcome.

Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

A.8.24 Use of cryptography mostly match
prevents

Mandates use of approved cryptographic algorithms, directly preventing weak-hash selection.

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing can detect weak-hash usage but does not prescribe algorithm choice.

A.8.26 Application security requirements partial match
prevents

Application security requirements can specify strong hashing, but the control is broader.

A.8.28 Secure coding partial match
prevents

Requires secure coding standards that forbid weak hash functions in source code.
