Description

CVE-2024-11626 is a critical vulnerability in Progress Sitefinity, a popular content management system (CMS). This flaw stems from improper neutralization of input during CMS backend web page generation, leading to a potential Cross-Site Scripting (XSS) vulnerability. Specifically, attackers can inject malicious scripts into the administrative section of the Sitefinity CMS, allowing them to execute arbitrary code in the context of the logged-in administrator.

While the CVSS score of 8.4 highlights the severity of the vulnerability, the SOCRadar Vulnerability Risk Score (SVRS) stands at 34, indicating that this CVE is not yet actively exploited in the wild. Despite this, the potential impact of exploitation could be significant, leading to data breaches, website defacement, and other malicious activities.

Key Insights

• High Impact Potential: Successful exploitation of CVE-2024-11626 could grant attackers full control over the Sitefinity CMS, potentially leading to complete website compromise and the theft of sensitive information.
• Administrative Access: The vulnerability specifically targets the administrative section of Sitefinity, which implies that successful exploitation requires an attacker to first compromise a legitimate administrator account.
• Wide Impact: The vulnerability affects multiple versions of Sitefinity, spanning from 4.0 through 15.2.8421, indicating a large potential attack surface.
• Potential for Chain Exploitation: An attacker could use CVE-2024-11626 as a stepping stone to gain access to other internal systems, especially if Sitefinity is used to manage a website with sensitive data or access to other corporate networks.

Mitigation Strategies

• Patching: The most effective mitigation strategy is to immediately apply the latest security patches released by Progress Software for Sitefinity. This will address the vulnerability and prevent any potential exploitation.
• Input Validation: Implement robust input validation mechanisms for all user-supplied data, especially in the Sitefinity administrative section. This prevents malicious scripts from being injected and executed.
• Security Awareness Training: Educate administrators and other users of Sitefinity about the importance of secure passwords, avoiding suspicious links, and reporting any unusual activity.
• Web Application Firewall (WAF): Deploy a WAF to block known XSS attacks and protect against other web-based threats, adding an additional layer of security.
