CVE-2024-28160 in iceScrum Plugin
Summary
by MITRE • 03/06/2024
Jenkins iceScrum Plugin 1.1.6 and earlier does not sanitize iceScrum project URLs on build views, resulting in a stored cross-site scripting (XSS) vulnerability exploitable by attackers able to configure jobs.

The vulnerability identified as CVE-2024-28160 affects the iceScrum plugin version 1.1.6 and earlier within the Jenkins continuous integration platform. This issue represents a critical security flaw that undermines the integrity of build views and exposes systems to malicious cross-site scripting attacks. The vulnerability stems from insufficient input validation and sanitization mechanisms within the plugin's handling of iceScrum project URLs, creating an environment where attacker-controlled data can be persistently stored and subsequently executed within the context of legitimate user sessions.
The technical flaw manifests as a stored XSS vulnerability that occurs when the iceScrum plugin fails to properly sanitize user-supplied URLs before rendering them in build view pages. When administrators or users configure jobs that reference iceScrum projects with maliciously crafted URLs, the plugin stores these unvalidated inputs without adequate sanitization. This stored data then gets rendered in subsequent build views, creating a persistent XSS vector that can be exploited by attackers who have the ability to configure jobs within the Jenkins environment. The vulnerability specifically targets the plugin's user interface rendering logic where project URLs are displayed without proper HTML escaping or validation.
The operational impact of this vulnerability extends beyond simple data corruption or information disclosure. Attackers with job configuration privileges can leverage this flaw to execute arbitrary JavaScript code in the browsers of users who view affected build pages. This capability enables a range of malicious activities including session hijacking, credential theft, redirection to malicious sites, and potential privilege escalation within the Jenkins environment. The stored nature of the vulnerability means that even users who do not directly interact with the compromised job configuration can be affected when they view build pages containing the malicious content, creating a widespread attack surface that can impact multiple users within an organization.
Mitigation strategies for CVE-2024-28160 should prioritize immediate plugin updates to versions that address the sanitization deficiency, as this represents the most effective solution to eliminate the vulnerability. Organizations should also implement restrictive access controls to limit job configuration privileges to only trusted personnel, thereby reducing the attack surface available to potential adversaries. Network-level protections such as content security policies and web application firewalls can provide additional layers of defense by blocking known malicious script patterns and preventing execution of unauthorized code. Security monitoring should be enhanced to detect anomalous job configuration activities and unusual URL patterns that might indicate exploitation attempts. This vulnerability aligns with CWE-79 which specifically addresses cross-site scripting flaws, and maps to ATT&CK technique T1566.001 for initial access through malicious web content, highlighting the need for comprehensive security measures across multiple defensive layers.
The broader implications of this vulnerability underscore the critical importance of input validation and sanitization in web applications, particularly within enterprise CI/CD platforms where multiple users interact with shared systems. Jenkins environments that utilize third-party plugins must maintain rigorous security hygiene practices including regular vulnerability assessments, plugin lifecycle management, and continuous monitoring of security advisories. The stored XSS nature of the vulnerability demonstrates how seemingly minor input handling flaws can create significant security risks in complex integrated systems where user data flows through multiple components before reaching end users. Organizations should also consider implementing automated security scanning tools that can detect similar sanitization issues across their entire Jenkins ecosystem and other web applications to prevent similar vulnerabilities from remaining undetected in production environments.
