CVE-2024-26163: CWE-693: Protection Mechanism Failure in Microsoft Microsoft Edge (Chromium-based)
Microsoft Edge (Chromium-based) Security Feature Bypass Vulnerability
AI Analysis
Technical Summary
CVE-2024-26163 is a medium-severity vulnerability identified in the Chromium-based Microsoft Edge browser. It is classified under CWE-693, which corresponds to a Protection Mechanism Failure. This type of vulnerability typically involves bypassing security controls designed to prevent unauthorized actions or access. Specifically, this vulnerability allows a security feature bypass in Microsoft Edge, meaning that an attacker could circumvent certain built-in protections of the browser. The CVSS v3.1 base score is 4.7, indicating a medium severity level. The vector string (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:N/I:L/A:N/E:U/RL:O/RC:C) reveals that the attack can be performed remotely over the network (AV:N) with low attack complexity (AC:L), requires no privileges (PR:N), but does require user interaction (UI:R). The scope is changed (S:C), meaning the vulnerability affects components beyond the initially vulnerable component. The impact is limited to a loss of integrity (I:L) without affecting confidentiality or availability. There are no known exploits in the wild as of the publication date, and no patches have been linked yet. The vulnerability affects version 1.0.0 of Microsoft Edge Chromium-based browser, which is an early or initial release version. The protection mechanism failure could allow attackers to bypass security features, potentially enabling them to manipulate browser behavior or content integrity, possibly leading to further exploitation or misleading users. However, the requirement for user interaction and the absence of privilege requirements somewhat limit the ease of exploitation and impact severity.
Potential Impact
For European organizations, this vulnerability poses a moderate risk primarily to the integrity of browser operations. Since Microsoft Edge is widely used across enterprises and public institutions in Europe, a successful bypass could allow attackers to manipulate web content or browser behavior, potentially facilitating phishing, social engineering, or delivery of further malicious payloads. The integrity loss could undermine trust in web applications accessed via Edge, especially in sectors relying on browser-based workflows such as finance, government, and healthcare. However, the lack of confidentiality or availability impact reduces the risk of data breaches or service disruption directly from this vulnerability. The requirement for user interaction means that targeted phishing or social engineering campaigns would likely be necessary to exploit this vulnerability, which could be a vector for attackers aiming at high-value targets. The absence of known exploits in the wild suggests that immediate widespread attacks are unlikely, but organizations should remain vigilant given the strategic importance of browser security.
Mitigation Recommendations
European organizations should prioritize updating Microsoft Edge to the latest available version once a patch addressing CVE-2024-26163 is released by Microsoft. Until then, organizations should implement enhanced user awareness training focusing on phishing and social engineering risks, as exploitation requires user interaction. Deploying endpoint protection solutions that monitor and block suspicious browser behaviors can help detect attempts to exploit this vulnerability. Network-level protections such as web filtering and intrusion detection systems should be tuned to identify and block known malicious URLs or payloads targeting Edge browsers. Additionally, organizations can consider applying application control policies to restrict the execution of untrusted scripts or extensions within Edge. Monitoring browser telemetry and logs for unusual activity related to browser integrity or unexpected content manipulation can provide early warning signs. Finally, maintaining a robust patch management process and subscribing to Microsoft security advisories will ensure timely response to updates.
