CVE-2024-29133

What it actually does

Out-of-bounds write vulnerability allowing memory corruption in Apache Commons Configuration versions 2.0 to before 2.10.1.

Why it matters to the business

Attackers may be able to corrupt application memory, leading to limited unauthorized data access or modification and potential service instability until fixed.

How an attack unfolds

An attacker with low-privileged network access crafts malicious configuration input that triggers the out-of-bounds write during processing, corrupting memory to achieve limited confidentiality or integrity impact.

How to fix it

Upgrade Apache Commons Configuration to version 2.10.1 or later. No fixed versions listed for gnutls/gnutls in the provided data.

How to confirm the fix worked

Verify the library version in use is 2.10.1 or newer and test that the previously vulnerable configuration parsing no longer exhibits out-of-bounds behavior.

Typical attack path

1. Identify an application using vulnerable Apache Commons Configuration
2. Send crafted configuration data over the network
3. Trigger parsing that performs the out-of-bounds write
4. Leverage resulting memory corruption for limited data exposure or tampering

How to detect it

Review application logs for unusual configuration parsing errors or memory-related crashes around the time of suspected exploitation; no specific public IOCs are available.

What your security team should do

• Immediately upgrade all instances of Apache Commons Configuration to 2.10.1
• Scan dependency manifests and rebuild pipelines for affected versions
• Monitor for any post-upgrade application behavior changes related to configuration handling
