CVE-2022-24112 is a critical vulnerability affecting Apache APISIX, a popular open-source API gateway. This vulnerability allows an attacker to exploit the batch-requests plugin to bypass the IP restriction of the Admin API. The default configuration of Apache APISIX, which utilizes a default API key, is particularly vulnerable to remote code execution. Although changing the admin key or altering the Admin API port can mitigate the impact, risks remain regarding the bypass of IP restrictions for the data panel.
The vulnerability is classified with a CVSS score of 9.8, indicating critical severity. The low attack complexity and lack of required privileges for exploitation make this vulnerability particularly alarming. Attackers may leverage this vulnerability to gain unauthorized access and execute arbitrary code, posing significant risks to organizations.
Organizations should prioritize patching immediately. The vulnerability was made public on February 11, 2022, and has been analyzed extensively. It is included in the Known Exploited Vulnerabilities (KEV) catalog, which indicates active exploitation in the wild.
Defenders must ensure that they are applying updates per vendor instructions to remediate this vulnerability effectively. The urgency for addressing this vulnerability cannot be overstated, as the potential for exploitation is high, and the consequences could be devastating.
Vulnerability Details
The vulnerability allows attackers to abuse the batch-requests plugin to send requests that bypass the IP restrictions of the Admin API. The default configuration of Apache APISIX (with the default API key) is vulnerable to remote code execution. When the admin key is changed or the port of the Admin API is modified, the risk is somewhat reduced, but vulnerabilities remain regarding bypassing the IP restrictions of the data panel.
The vulnerability is classified under CWE-290, indicating issues related to authentication bypass. The CVSS score of 9.8 reflects its critical nature, with high impacts on confidentiality, integrity, and availability.
Technical Analysis
The root cause of this vulnerability lies in a flaw within the batch-requests plugin, where a check intended to override the client IP with its real remote IP can be bypassed due to a bug in the code. This oversight allows unauthorized users to execute requests that should be restricted.
The attack vector is network-based, requiring no user interaction and no privileges, making it straightforward for attackers to exploit. The impacts of this vulnerability include high confidentiality, integrity, and availability risks, allowing attackers to potentially execute arbitrary code.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2022-24112 is significant. Organizations using Apache APISIX with default configurations are especially at risk. The potential blast radius is extensive, as attackers exploiting this vulnerability may gain unauthorized access to sensitive systems, leading to data breaches and service disruptions.
Organizations must evaluate their configurations and ensure proper security controls are in place. The urgency to address this vulnerability is critical, and organizations should adopt a proactive approach to patching and securing their API gateways.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | Yes |
Public PoC | Yes |
Actively Exploited | Yes |
Ransomware Use | No |
Affected Versions
The vulnerability affects all versions of Apache APISIX prior to 2.10.4 and those starting from 2.11.0 up to (but not including) 2.12.1. Organizations should ensure that they are using patched versions to mitigate risks.
Mitigation & Remediation
To mitigate this vulnerability, organizations should apply the latest updates provided by Apache. This includes upgrading to versions that are not affected by the vulnerability. Organizations should also review and modify their configurations to disable the default API key, utilize secure keys, and implement network controls to restrict access to the Admin API.
For comprehensive guidance, organizations may refer to the penetration testing services that can help identify and remediate similar vulnerabilities.
Detection Guidance
Organizations should monitor logs for any unauthorized access attempts to the Admin API and look for unusual patterns in the network traffic that may indicate exploitation attempts. Behavioral anomalies, such as unexpected changes in system configurations or unauthorized command executions, should also be flagged for further investigation.
AppSecure Threat Intelligence Insight
The long-term significance of CVE-2022-24112 lies in its demonstration of the vulnerabilities associated with default configurations in widely-used software. It highlights the importance of security practices, such as changing default credentials and implementing strict access controls. This incident serves as a reminder for security teams to regularly assess their systems and adopt a proactive approach to vulnerability management.
Organizations can improve their security posture by implementing a vulnerability management program that includes regular assessments and updates to security policies.
In conclusion, CVE-2022-24112 serves as a critical lesson for organizations to prioritize security and remain vigilant against emerging threats. By staying informed and adapting to the evolving threat landscape, organizations can better protect their assets and maintain the integrity of their systems.
