CVE-2024-46901 | Apache Subversion: mod_dav_svn denial-of-service via control characters in paths

Exp

Insufficient validation of filenames against control characters in Apache Subversion repositories served via mod_dav_svn allows authenticated users with commit access to commit a corrupted revision, leading to disruption for users of the repository. All versions of Subversion up to and including Subversion 1.14.4 are affected if serving repositories via mod_dav_svn. Users are recommended to upgrade to version 1.14.5, which fixes this issue. Repositories served via other access methods are not affected.

Base score Version Severity Vector Exploitability Impact Score source
3.1 3.1 LOW
CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:L Click to expand
Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:H)
Even with access, the exploit needs extra luck, timing, or a fussy environment to actually work.
Privileges required (PR:L)
A normal user session is enough; they don’t have to be admin.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:N)
Doesn’t really leak secrets in a meaningful way.
Integrity (I:N)
Data isn’t meaningfully altered or forged.
Availability (A:L)
Might cause slowdowns, glitches, or partial disruption—not a full brick.
