CVE-2024-3801: In-Depth Analysis and Mitigation Strategies for Enhanced Cybersecurity

Executive Summary

CVE-2024-3801 is a recently identified vulnerability in the S@M CMS (Concept Intermedia) software, which allows for Reflected Cross-Site Scripting (XSS) attacks. This vulnerability, with a CVSS base score of 6.1, poses a moderate risk to organizations using this software. Attackers can exploit this vulnerability by injecting malicious scripts into web pages viewed by other users, potentially leading to session hijacking, defacement, or redirection to malicious sites. While there have been no specific reports of this vulnerability being exploited in the wild, the nature of Reflected XSS vulnerabilities suggests that it could be leveraged by attackers to execute arbitrary JavaScript in the context of the user's browser.

Technical Information

Vulnerability Type: Reflected Cross-Site Scripting (XSS)

Affected Software: S@M CMS (Concept Intermedia)

Attack Vector: Remote

CVE ID: CVE-2024-3801

CVSS Score: 6.1 (Moderate)

Description: CVE-2024-3801 is a vulnerability that allows attackers to inject malicious scripts into web pages viewed by other users. This is achieved by manipulating the GET parameters in HTTP requests. When a user clicks on a malicious link or visits a compromised website, the injected script is executed in the context of the user's browser, potentially leading to session hijacking, defacement, or redirection to malicious sites.

The vulnerability exists in the way the S@M CMS software handles input from GET parameters. By crafting a malicious URL that includes a script in one of the GET parameters, an attacker can trick the server into reflecting the script back to the user's browser. This type of attack is known as Reflected XSS because the malicious script is reflected off the server and executed in the user's browser.

Technical Details: The vulnerability is present in versions up to and including 3.3 of the S@M CMS software. The attack vector is remote, meaning that an attacker can exploit the vulnerability from anywhere on the internet. The CVSS score of 6.1 indicates a moderate level of severity, reflecting the potential impact of the vulnerability on affected systems.

Exploitation in the Wild

There have been no specific reports of CVE-2024-3801 being exploited in the wild. However, the nature of Reflected XSS vulnerabilities suggests that attackers could potentially use this vulnerability to execute arbitrary JavaScript in the context of the user's browser. This could lead to session hijacking, defacement, or redirection to malicious sites. Indicators of Compromise (IOCs) for this vulnerability include unusual GET requests with script tags in the parameters, unexpected JavaScript execution in user sessions, and reports from users about being redirected to unknown or malicious sites.

APT Groups using this vulnerability

While there are no specific APT groups publicly attributed to exploiting CVE-2024-3801, the techniques used are consistent with those employed by groups known for web-based attacks, such as APT28 and APT32. These groups have a history of using web-based vulnerabilities to achieve their objectives, which often include espionage, data theft, and disruption of services. Organizations in sectors such as government, finance, and critical infrastructure should be particularly vigilant, as these sectors are often targeted by APT groups.

Affected Product Versions

The affected product versions include S@M CMS (Concept Intermedia) versions up to and including 3.3. Organizations using these versions of the software are at risk and should take immediate action to mitigate the vulnerability.

Workaround and Mitigation

To mitigate the risk posed by CVE-2024-3801, organizations should implement the following strategies:

Input Validation: Implement strict input validation to ensure that data received from GET parameters is sanitized. This can help prevent malicious scripts from being injected into web pages.

Content Security Policy (CSP): Deploy a robust Content Security Policy to restrict the execution of scripts. CSP can help prevent the execution of malicious scripts by specifying which sources of content are allowed to be loaded and executed.

Security Patches: Apply any available patches or updates provided by Concept Intermedia for the S@M CMS software. Keeping software up-to-date is one of the most effective ways to mitigate vulnerabilities.

Web Application Firewall (WAF): Configure a WAF to detect and block malicious requests that attempt to exploit this vulnerability. A WAF can provide an additional layer of protection by filtering out malicious traffic before it reaches the web server.
