CVE-2024-8373: Medium Vulnerability in AngularJS and NetApp Active IQ Unified Manager

CVE-2024-8373 is classified as a medium-severity vulnerability affecting AngularJS and NetApp's Active IQ Unified Manager. This vulnerability allows attackers to exploit improper sanitization of the value of the [srcset] attribute in <source> HTML elements. As a result, attackers can bypass common image source restrictions, potentially leading to a form of Content Spoofing. This issue affects all versions of AngularJS, which is critical as the project is end-of-life and will not receive any updates to address this issue. Organizations using AngularJS should consider the risks and plan for migration or mitigation strategies.

The vulnerability has a CVSS score of 4.8, which indicates a medium severity level. Its exploitability is considered medium, emphasizing the importance of addressing this issue in a timely manner. As the AngularJS framework is phased out, organizations should prioritize transitioning to supported alternatives to maintain application security.

Risk to organizations includes potential unauthorized access to sensitive data, as attackers might leverage this vulnerability for malicious purposes. It is crucial for security teams to understand the implications of this vulnerability and to take proactive measures to protect their applications.

Organizations should monitor their systems for any indicators of compromise and ensure that they are prepared to respond swiftly to mitigate any potential impact from this vulnerability.

Vulnerability Details

The official description for CVE-2024-8373 states that improper sanitization of the value of the [srcset] attribute in <source> HTML elements in AngularJS allows attackers to bypass common image source restrictions, leading to content spoofing. The CVSS score of 4.8 indicates a medium severity level, with an attack vector categorized as NETWORK and a high attack complexity.

The affected products include AngularJS and Active IQ Unified Manager, with no known public exploits. The vulnerability was published on September 9, 2024.

Technical Analysis

The root cause of CVE-2024-8373 revolves around the improper sanitization of the [srcset] attribute, which allows for the inclusion of potentially harmful image sources. The attack vector is classified as NETWORK, meaning that an attacker can exploit this vulnerability remotely.

Attack complexity is high, meaning that an attacker would need to craft a specific payload to exploit this vulnerability successfully. No user interaction is required, and the attacker does not need any privileges to exploit this vulnerability.

The impacts on confidentiality, integrity, and availability are classified as NONE, LOW, and LOW, respectively. This indicates that while the attack may not compromise confidentiality, it can still affect the integrity of web content.

Risk & Impact Analysis

The real-world deployment risk associated with CVE-2024-8373 is significant, particularly for organizations that maintain legacy applications using AngularJS. The potential for content spoofing can lead to a loss of trust among users and customers, ultimately impacting business reputation.

Organizations should evaluate the blast radius of this vulnerability, especially if they are using AngularJS in critical web applications. The urgency to address this vulnerability is underscored by its classification as medium severity and the fact that AngularJS will not receive further updates.

Affected Versions

All versions of AngularJS are affected by this vulnerability. Additionally, all versions of NetApp's Active IQ Unified Manager are also vulnerable. As AngularJS is end-of-life, organizations should seek alternatives and plan to migrate away from using this framework.

Mitigation & Remediation

Organizations should prioritize patching by migrating away from AngularJS to supported frameworks. Given that AngularJS will not receive updates, this is a critical step in maintaining application security. For those using Active IQ Unified Manager, ensure you are using the latest version available and follow any vendor-specific recommendations.

Additionally, implementing configuration hardening and network controls can help mitigate potential exploit vectors. Continuous monitoring for behavioral anomalies related to this vulnerability is also recommended.

Penetration testing can help assess the effectiveness of your mitigation strategies and identify any additional vulnerabilities.

Detection Guidance

Security teams should monitor logs for any unusual activity related to image sources. Behavioral anomalies, such as unexpected content serving from known image paths, should be flagged for investigation.

Network signatures that detect unauthorized image requests or modifications can further aid in the detection of exploitation attempts.

AppSecure Threat Intelligence Insight

CVE-2024-8373 highlights the challenges associated with maintaining legacy systems, particularly those that are no longer supported. This vulnerability serves as a reminder for organizations to prioritize the lifecycle management of their software and frameworks.
