CVE-2024-45720:
Apache Subversion vulnerability analysis and mitigation
Overview
CVE-2024-45720 is a command line argument injection vulnerability affecting Apache Subversion (SVN) on Windows platforms. The vulnerability was discovered in October 2024 and affects all versions of Subversion up to and including version 1.14.3 on Windows systems. The flaw stems from a "best fit" character encoding conversion of command line arguments to Subversion's executables (e.g., svn.exe) that may lead to unexpected command line argument interpretation (Vendor Advisory, Security Online).
Technical details
The vulnerability arises from how Windows handles command line arguments differently from UNIX-like platforms. On Windows, command line arguments are passed to a program as a single string, which the program must parse into individual arguments. During this process, a "best fit" character encoding conversion occurs, particularly when certain Unicode characters are involved, which can lead to unpredictable outcomes. The vulnerability has been assigned a CVSS v3.1 base score of 8.2 (High) with the vector string CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H (NVD).
Impact
If exploited, this vulnerability could allow an attacker who can run one of Subversion's executables with a specially crafted command line argument string to cause unexpected command line argument interpretation, leading to argument injection and execution of other programs. The issue primarily affects Windows 10 and 11, though it may impact most other Windows versions as well (Security Online).
Mitigation and workarounds
Users are strongly recommended to upgrade to Subversion version 1.14.4, which contains the fix for this vulnerability. For those unable to immediately upgrade, a patch is available from the Subversion project (Vendor Advisory).
