CVE-2024-8372 is a vulnerability classified under CWE-1289, which concerns improper validation of unsafe equivalence in input. Specifically, this issue affects the AngularJS framework's handling of the 'srcset' attribute in HTML image elements. The vulnerability arises because AngularJS does not properly sanitize or validate the 'srcset' attribute's value, allowing attackers to bypass common image source restrictions. This can lead to content spoofing attacks, where malicious actors manipulate displayed content to deceive users, potentially facilitating phishing or social engineering. The flaw affects all AngularJS versions starting from 1.3.0-rc.4 onward. Since AngularJS has reached its end-of-life status, no official patches or updates will be released to address this vulnerability. The CVSS v3.1 score of 4.8 reflects a medium severity, with network attack vector, high attack complexity, no privileges required, no user interaction, and an impact limited to integrity and availability but not confidentiality. No known exploits are currently reported in the wild. The vulnerability's exploitation could allow attackers to inject or manipulate image sources in web applications, undermining trust and potentially disrupting service availability or integrity of displayed content. Given AngularJS's widespread historical use in enterprise web applications, especially legacy systems, this vulnerability poses a risk to organizations that have not migrated to newer frameworks or applied compensating controls.

For European organizations, the impact of CVE-2024-8372 primarily involves the risk of content spoofing and potential disruption of web application integrity and availability. Organizations relying on legacy AngularJS applications for customer-facing portals, internal dashboards, or critical web services may experience reputational damage if attackers exploit this flaw to display misleading images or content. Although confidentiality is not directly impacted, the integrity and availability of web content can be compromised, potentially leading to user mistrust or operational interruptions. Sectors such as finance, government, healthcare, and e-commerce, which often maintain legacy web applications, are particularly vulnerable. The lack of vendor patches due to AngularJS's end-of-life status increases the risk exposure, as organizations must rely on alternative mitigation strategies. Additionally, attackers could leverage this vulnerability as part of broader social engineering or phishing campaigns targeting European users, amplifying the threat's impact.

Given the absence of official patches, European organizations should prioritize migrating away from AngularJS to actively supported frameworks such as Angular (2+), React, or Vue.js to eliminate the vulnerability. In the interim, organizations should implement strict input validation and sanitization on the server side to ensure that any 'srcset' attribute values are safe and conform to expected patterns. Employing Content Security Policies (CSP) that restrict image sources to trusted domains can reduce the risk of malicious content injection. Web application firewalls (WAFs) can be configured to detect and block suspicious payloads targeting the 'srcset' attribute. Regular security audits and code reviews focusing on legacy AngularJS applications should be conducted to identify and remediate unsafe input handling. User awareness training about phishing and content spoofing can help mitigate social engineering risks. Finally, monitoring web application logs for anomalous requests involving image attributes can provide early detection of exploitation attempts.
