CVE-2024-45720
📋 TL;DR
On Windows, Subversion's command-line argument processing can misinterpret specially crafted arguments due to character encoding issues, potentially allowing attackers to inject and execute arbitrary commands. This affects all Subversion versions up to 1.14.3 on Windows platforms only. UNIX-like systems are not vulnerable.
💻 Affected Systems
- Subversion (svn)
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Remote code execution with the privileges of the Subversion process, potentially leading to full system compromise.
Likely Case
Local privilege escalation or command injection when users run Subversion with untrusted command-line arguments.
If Mitigated
Limited impact if Subversion is used only with trusted inputs and proper access controls.
🎯 Exploit Status
Exploitation requires crafting specific command-line arguments and likely local access or social engineering.
🛠️ Fix & Mitigation

Patch Version: Subversion 1.14.4
Vendor Advisory: https://subversion.apache.org/security/CVE-2024-45720-advisory.txt
Restart Required: No
Instructions:
1. Download Subversion 1.14.4 or later from the official Apache Subversion website. 2. Uninstall the old version. 3. Install the new version. 4. Verify the update with 'svn --version'.
🔧 Temporary Workarounds
Avoid untrusted command-line arguments
windowsDo not run Subversion with command-line arguments from untrusted sources.
Use Subversion on UNIX-like systems
allIf possible, use Subversion on Linux or macOS where this vulnerability does not exist.
🧯 If You Can't Patch
- Restrict Subversion usage to trusted users and inputs only.
- Monitor for unusual Subversion process activity or command-line arguments.
🔍 How to Verify
Check if Vulnerable:
Check if Subversion version is 1.14.3 or earlier on Windows.Check Version:
svn --versionVerify Fix Applied:
Confirm Subversion version is 1.14.4 or later.📡 Detection & Monitoring
Log Indicators:
- Unusual command-line arguments passed to svn.exe
- Unexpected process execution from Subversion
SIEM Query:
Process creation where command line contains 'svn.exe' and arguments with unusual characters or patterns.
