Summary

CVE-2026-2401 is a low-severity Insertion of Sensitive Information into Log File (CWE-532) vulnerability in Schneider-Electric Powerchute Serial Shutdown. Its CVSS base score is 2.4 (Low).

Operationally, exploitation aligns with the MITRE ATT&CK technique Credentials In Files (T1552.001); ranked at the 1th 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 AC-6 (Least Privilege) and SI-3 (Malicious Code Protection) — see the control section below for these in your framework.

Vulnerability Data

CWE-532 Insertion of Sensitive Information into Log File vulnerability exists that could cause confidential information to be exposed when a Web Admin user executes a malicious file provided by an attacker.

CWE(s)

Related Threats

MITRE ATT&CK Enterprise TechniquesAI

T1552.001 Credentials In Files Credential Access
Adversaries may search local file systems and remote file shares for files containing insecurely stored credentials.
Why these techniques?

CWE-532 directly results in sensitive data (commonly credentials) being written to log files on disk, enabling T1552.001 when those files are later read.

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly protects log files containing sensitive information from unauthorized exposure after insertion.

prevent

Limits Web Admin privileges to reduce ability to execute attacker-supplied malicious files that trigger sensitive logging.

prevent

Blocks execution of malicious files that cause the Web Admin action resulting in sensitive data being written to logs.

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 mostly match
prevents

Secure SDLC practices directly prohibit writing sensitive data to logs; eliminating the weakness satisfies only one narrow slice of the control.

PR.PS-04 partial match
prevents

Log generation configuration can and should exclude sensitive data, but the control statement focuses on availability rather than content filtering.

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.8.15 Logging mostly match
prevents

Requiring de-identification and privacy controls before logs leave the organization reduces the chance that sensitive data inadvertently captured in logs becomes exposed to external parties.

mitigates

By defining what records must be kept, where, and for how long, the control discourages the inadvertent inclusion of sensitive information in logs or other externally accessible files that fall outside the formal record system.

mitigates

Mandating deletion of temporary files and logs that may contain sensitive information prevents those artifacts from remaining accessible after the data is no longer needed.

A.8.11 Data masking partial match
mitigates

When log entries are produced from masked data sets, the control prevents the inadvertent insertion of sensitive values into externally accessible log files.

mitigates

DLP inspection of logs and file transfers can detect and block the inadvertent placement of sensitive tokens or credentials into externally accessible log files before they are written or transmitted.

prevents

Requiring restrictions on free-text fields and proper error-message handling stops developers from embedding or leaking sensitive data into logs or diagnostic output.
