Apache Subversion ≤ 1.14.5
Raw vector
CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:LSummary
CVE-2024-46901 is a low-severity Improper Input Validation (CWE-20) vulnerability in Apache Subversion. Its CVSS base score is 3.1 (Low).
Operationally, exploitation aligns with the MITRE ATT&CK technique Content Injection (T1659); ranked in the top 22% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2024-46901 is an insufficient input validation flaw (CWE-20, CWE-116) in Apache Subversion that affects filename handling against control characters. It impacts all versions up to and including 1.14.4 when repositories are served through the mod_dav_svn module; repositories accessed by other means are unaffected. An authenticated user with commit rights can introduce a corrupted revision that disrupts subsequent repository operations for all users.
An attacker with existing commit access can exploit the weakness over the network to upload a specially crafted filename containing control characters. Successful exploitation results in a corrupted revision that causes denial-of-service effects for other repository users, though the CVSS score of 3.1 reflects the high attack complexity and limited impact.
Advisories recommend upgrading to Subversion 1.14.5, which contains the fix. The Debian LTS announcement further details backported packages for affected distributions.
The EPSS score rose from a low baseline to a peak of 0.1250 on 2025-12-11 before receding to the current value of 0.0581, indicating a period of increased exploitation interest after disclosure.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation can discover missing input validation through analysis or test cases.
SI-10 directly requires validity checks on information inputs, structurally preventing improper or missing validation.
Requiring documented development standards and tools can embed input-validation practices into the engineering process.

Secure coding standards explicitly require correct output encoding and escaping to preserve message structure.
Testing against a defined set of requirements and using code review plus vulnerability scanning forces validation of inputs and handling of unanticipated conditions, reducing the chance that malformed data will be accepted.
Secure-coding guidelines and mandatory security testing (including code scans) compel developers to validate and sanitize inputs at design and implementation time, lowering the incidence of malformed or malicious data reaching downstream components.
Mandating input controls that include integrity checks and input validation ensures that untrusted data is examined before use, blocking the root cause of many injection and malformed-data weaknesses.
Security-by-design principles explicitly call for data validation and sanitization at every layer, reducing the chance that malformed or malicious input will be processed without scrutiny.
Regular automated validation of system software and data content, combined with scanning of all inbound files, enforces input validation at the boundary before untrusted content is processed.
