Summary

CVE-2026-22543 is a medium-severity Weak Encoding for Password (CWE-261) vulnerability in Thalesgroup (inferred from references). Its CVSS base score is 6.9 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Unsecured Credentials (T1552); ranked at the 8th 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) and IA-5 (Authenticator Management) — see the control section below for these in your framework.

Vulnerability Data

The credentials required to access the device's web server are sent in base64 within the HTTP headers. Since base64 is not considered a strong cipher, an attacker could intercept the web request handling the login and obtain the credentials

Mitigating Controls (NIST 800-53 r5) AI

SC-13 Cryptographic Protection good match

Cryptographic protection mandates approved algorithms and key management that preclude weak encoding schemes for sensitive data such as passwords.

IA-5 Authenticator Management partial match

Authenticator management requires secure generation, storage, and distribution of passwords rather than trivial encoding.

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.DS-01 mostly match
prevents

Proper cryptographic hashing for data-at-rest directly prevents trivial password encoding while the control addresses broader data protection needs.

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

Requires appropriate use of cryptography, indirectly discouraging weak encoding schemes.

A.5.17 Authentication information partial match
degrades

Requires secure handling and protection of authentication information, directly addressing weak password encoding.

A.8.28 Secure coding partial match
prevents

Enforces secure coding practices that would reject trivial password encoding.

A.8.5 Secure authentication partial match
degrades

Mandates secure authentication mechanisms, which precludes trivial encoding of passwords.
