Summary

CVE-2024-11999 is a high-severity Use of Unmaintained Third Party Components (CWE-1104) vulnerability in Schneider Electric (inferred from references). Its CVSS base score is 8.7 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Data Obfuscation (T1001); ranked at the 49th 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 SA-22 (Unsupported System Components) — see the control section below for these in your framework.

MITRE ATT&CK Enterprise Techniques

T1001 Data Obfuscation Command And Control
Adversaries may obfuscate command and control traffic to make it more difficult to detect.
attack.mitre.org →
T1003.004 LSA Secrets Credential Access
Adversaries with SYSTEM access to a host may attempt to access Local Security Authority (LSA) secrets, which can contain a variety of different credential materials, such as credentials for service accounts.

Mitigating Controls (NIST 800-53 r5) AI

SA-22 Unsupported System Components good match

SA-22 directly requires replacing components once vendor support ends, structurally preventing reliance on unmaintained third-party code.

GV.RM-04 partial match
blocks

GV.RM-04's high-level risk-response criteria can indirectly discourage unmaintained third-party use via policy, but alone removes none of the concrete supply-chain or maintenance decisions that produce CWE-1104.

A maintained asset inventory plus scheduled scanning and patching directly reduces the window during which known vulnerable third-party components remain exploitable.
