Summary

CVE-2025-47276 is a high-severity Use of Weak Hash (CWE-328) vulnerability in Owasp (inferred from references). Its CVSS base score is 7.5 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique OS Credential Dumping (T1003); ranked at the 19th 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

Actualizer is a single shell script solution to allow developers and embedded engineers to create Debian operating systems (OS). Prior to version 1.2.0, Actualizer uses OpenSSL's "-passwd" function, which uses SHA512 instead of a more suitable password hasher like Yescript/Argon2i.…

more

All Actualizer users building a full Debian Operating System are affected. Users should upgrade to version 1.2.0 of Actualizer. Existing OS deployment requires manual password changes against the alpha and root accounts. The change will deploy's Debian's yescript overriding the older SHA512 hash created by OpenSSL. As a workaround, users need to reset both `root` and "Alpha" users' passwords.

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.

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.
