CVE-2022-29158 : Security Advisory and Response

Apache OFBiz up to version 18.12.05 is vulnerable to Regular Expression Denial of Service (ReDoS) due to inefficient regular expression complexity in handling URLs provided by external, unauthenticated users. Learn about the impact, technical details, and mitigation strategies.

Understanding CVE-2022-29158

This CVE pertains to a vulnerability in Apache OFBiz that allows attackers to launch Regular Expression Denial of Service (ReDoS) attacks by exploiting the way the software processes URLs from unauthenticated users.

What is CVE-2022-29158?

CVE-2022-29158 is a security flaw in Apache OFBiz versions up to 18.12.05 that exposes systems to ReDoS attacks. Attackers can exploit this vulnerability by providing maliciously crafted URLs, causing resource exhaustion and potential denial of service.

The Impact of CVE-2022-29158

The impact of CVE-2022-29158 includes potential downtime, service unavailability, and system instability. Attackers can leverage this vulnerability to disrupt normal system operation, leading to adverse effects on businesses and users.

Technical Details of CVE-2022-29158

Vulnerability Description

The vulnerability in Apache OFBiz arises from inefficient regular expression complexity when processing URLs. This inefficiency allows attackers to create specially crafted URLs to trigger excessive computation, leading to resource exhaustion and service disruption.

Affected Systems and Versions

Apache OFBiz versions up to 18.12.05 are affected by this vulnerability. Users operating on these versions are at risk of exploitation by malicious actors intending to launch ReDoS attacks.

Exploitation Mechanism

Attackers can exploit CVE-2022-29158 by sending specially crafted URLs to Apache OFBiz instances. By manipulating the regular expression processing of these URLs, attackers can cause the system to consume excessive resources, resulting in denial of service.

Mitigation and Prevention

Immediate Steps to Take

To mitigate the risks associated with CVE-2022-29158, users are strongly advised to upgrade their Apache OFBiz installations to version 18.12.06. Alternatively, users can apply patches provided by Apache to address the vulnerability and enhance system security.

Long-Term Security Practices

In the long term, it is essential for organizations to regularly update and patch their software to protect against known vulnerabilities. Implementing robust security measures, such as input validation and access control, can also help prevent ReDoS attacks and other security threats.

Patching and Updates

Regularly monitoring for security updates and applying patches promptly is crucial for maintaining the security of Apache OFBiz deployments. By staying informed about security advisories from Apache Software Foundation, users can stay ahead of potential threats and safeguard their systems.
