CVE-2024-2597 in AMSS++
Summary
by MITRE • 03/18/2024
Vulnerability in AMSS++ version 4.31, which does not sufficiently encode user-controlled input, resulting in a Cross-Site Scripting (XSS) vulnerability through /amssplus/modules/book/main/bookdetail_school_person.php, in the 'b_id' parameter. This vulnerability could allow a remote attacker to send a specially crafted URL to an authenticated user and steal their session cookie credentials.

The vulnerability identified as CVE-2024-2597 resides within the AMSS++ version 4.31 software platform, specifically affecting the bookdetail_school_person.php module. This represents a critical cross-site scripting flaw that stems from inadequate input validation and encoding mechanisms within the application's processing pipeline. The vulnerability manifests through the 'b_id' parameter, which serves as an entry point for malicious input manipulation. The flaw allows attackers to inject malicious scripts into the application's response, creating a persistent threat vector that can be exploited by remote adversaries.
The technical implementation of this vulnerability aligns with CWE-79, which specifically addresses cross-site scripting weaknesses in web applications. When user-controlled input containing malicious script code is passed through the 'b_id' parameter without proper sanitization or encoding, the application fails to properly escape special characters that could otherwise be interpreted as executable code by web browsers. This processing gap creates an environment where attacker-controlled data can be executed in the context of authenticated user sessions, bypassing standard security boundaries and access controls.
The operational impact of this vulnerability extends beyond simple script injection, as it enables session hijacking through cookie theft mechanisms. An attacker can craft a malicious URL containing encoded script payloads that, when executed in an authenticated user's browser, can steal session cookies and potentially gain unauthorized access to user accounts. This type of attack follows patterns consistent with ATT&CK technique T1539, which involves stealing credentials from web browsers, and demonstrates how XSS vulnerabilities can serve as initial access vectors for more sophisticated attacks. The authenticated nature of the target means that successful exploitation can provide access to sensitive educational data and user account information.
Mitigation strategies for CVE-2024-2597 must address both the immediate input validation gaps and implement comprehensive security measures. The primary recommendation involves implementing strict input validation and output encoding mechanisms, particularly for all parameters passed through the bookdetail_school_person.php module. This includes applying proper HTML entity encoding to all user-supplied data before rendering it in web responses, which directly addresses the root cause of the vulnerability. Additionally, implementing Content Security Policy headers can provide an additional layer of protection against script execution, while regular security audits of input handling mechanisms can help identify similar vulnerabilities in other parts of the application. The remediation should also include implementing proper session management controls and monitoring for suspicious user activities that may indicate exploitation attempts.
