CVE-2022-30958 is a high-severity cross-site request forgery (CSRF) vulnerability found in Jenkins SSH Plugin versions 2.6.1 and earlier. This vulnerability allows attackers to connect to an attacker-specified SSH server using attacker-specified credential IDs obtained through other means. The potential impact includes the compromise of credentials stored in Jenkins, making it a serious concern for organizations using this software.
With a CVSS score of 8.8, this vulnerability is classified as high severity. Organizations should prioritize patching immediately to protect against potential exploits. This vulnerability is particularly concerning as it can lead to unauthorized access and exposure of sensitive information.
The vulnerability was published on May 17, 2022, and has been marked as modified in its status. As of now, there are no known exploits or public proof-of-concept (PoC) available. However, the nature of the vulnerability poses a significant risk, especially if exploited in the wild.
Organizations leveraging Jenkins should assess their exposure to this vulnerability and ensure that they are using versions of the SSH Plugin that have been patched. The urgency to address this vulnerability cannot be understated, as it could result in severe ramifications if left unmitigated.
Vulnerability Details
The official description states that this vulnerability allows attackers to connect to an attacker-specified SSH server using attacker-specified credentials IDs obtained through another method, capturing credentials stored in Jenkins. This vulnerability falls under the CWE-352 classification.
The affected product is the Jenkins SSH Plugin, specifically versions 2.6.1 and earlier. The vulnerability was published on May 17, 2022, and has a CVSS score of 8.8, indicating a high severity level due to its potential impact on confidentiality, integrity, and availability.
Technical Analysis
The root cause of this vulnerability stems from the lack of proper validation for requests made to the Jenkins SSH Plugin. Specifically, it is susceptible to CSRF attacks, allowing malicious actors to deceive authenticated users into executing unintended actions.
The attack vector for this vulnerability is the network, with low attack complexity. No privileges are required to exploit this vulnerability, but user interaction is necessary, as the user must be tricked into executing the request. This vulnerability has a high impact on confidentiality, integrity, and availability.
Risk & Impact Analysis
Risk to organizations includes unauthorized access to sensitive credentials stored in Jenkins, leading to potential breaches and exploitation of other systems. The vulnerability's high CVSS score indicates a significant risk that organizations must address promptly.
Organizations should assess the potential blast radius of this vulnerability, especially if Jenkins is integrated with other critical systems. The urgency for mitigation is high, given the potential for widespread impact.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
The vulnerability affects Jenkins SSH Plugin versions 2.6.1 and earlier. Organizations should ensure they are using an updated version to mitigate the risks associated with this vulnerability.
Mitigation & Remediation
Organizations should prioritize patching Jenkins SSH Plugin to the latest version where this vulnerability is fixed. If immediate patching is not possible, organizations can implement workarounds such as restricting access to the Jenkins instance, applying network controls, and monitoring for unauthorized access attempts.
For further guidance on security practices, organizations may refer to penetration testing services to assess their security posture.
Detection Guidance
Organizations should monitor logs for unusual activities, specifically focusing on attempts to access SSH servers unexpectedly. Behavioral anomalies in user interactions with Jenkins should also be observed to detect potential exploitation attempts.
AppSecure Threat Intelligence Insight
The long-term significance of CVE-2022-30958 highlights the importance of validating user inputs and ensuring robust security measures against CSRF vulnerabilities. As organizations increasingly rely on tools like Jenkins for continuous integration and deployment, the lessons learned from this vulnerability should inform security practices.
This vulnerability represents a common pattern in web application security where CSRF can lead to unauthorized actions by authenticated users. Security teams should implement comprehensive security measures, including CSRF tokens and thorough user validation, to safeguard against similar vulnerabilities in the future.
For further insights on application security, organizations can explore resources on vulnerability management programs and best practices in penetration testing methodology to enhance their security posture.
Additionally, organizations should stay informed about emerging threats and vulnerabilities to proactively address security challenges in their environments.
