Jenkins Nested View Plugin versions 1.20 through 1.25 (inclusive) contains a reflected cross-site scripting (XSS) vulnerability due to improper escaping of search parameters. This vulnerability allows attackers to inject malicious scripts that may execute in a user's browser, potentially compromising sensitive information and user sessions.
The CVSS score for this vulnerability is 6.1, categorizing it as medium severity. Given the nature of XSS vulnerabilities, the risk to organizations includes unauthorized access to sensitive data, session hijacking, and redirection to malicious sites. Organizations should address this vulnerability in their priority patch cycle to mitigate potential threats.
As of now, no known exploits are available, and it is not included in the Known Exploited Vulnerabilities (KEV) catalog. However, the presence of this vulnerability in widely used software necessitates immediate attention from security teams.
Organizations using Jenkins should prioritize patching immediately to prevent exploitation. The urgency is heightened by the fact that user interaction is required for the attack to succeed, making social engineering tactics a potential vector.
Vulnerability Details
The vulnerability allows for reflected cross-site scripting (XSS), which is classified under CWE-79. This occurs when untrusted input is reflected back to the user without proper validation or escaping, allowing the execution of arbitrary scripts in the user's browser context.
The affected versions of the Jenkins Nested View Plugin are 1.20 to 1.25, and the vulnerability was published on June 23, 2022. Given the potential impact of XSS vulnerabilities, organizations should take this matter seriously.
Technical Analysis
The root cause of this vulnerability lies in the failure to escape search parameters used within the Jenkins Nested View Plugin. Attackers may exploit this by crafting a malicious URL that, when accessed by the victim, executes scripts within their browser.
The attack vector is network-based, requiring the victim to interact with a malicious link. The attack complexity is low, and no privileges are required to exploit this vulnerability. User interaction is necessary, as the attacker must trick the user into clicking the malicious link.
Confidentiality and integrity impacts are both classified as low, while availability impact is none. This indicates that while data may not be directly compromised, the attack can lead to significant privacy breaches and unauthorized actions on behalf of users.
Risk & Impact Analysis
The real-world risk posed by this vulnerability is significant, as reflected XSS vulnerabilities are commonly exploited in various attack scenarios, including phishing and session hijacking. The urgency for organizations is high, as attackers may leverage social engineering tactics to exploit unaware users.
Organizations must understand the blast radius of this vulnerability, as the impact can extend to all users of the Jenkins system, especially those who have access to sensitive functionalities.
Given that the exploitation complexity is low and user interaction is required, organizations should focus on educating users about the risks associated with clicking unknown links. The combination of user education and immediate patching of affected systems is essential to mitigate risks.
