CVE-2025-54246 is an Incorrect Authorization vulnerability (CWE-863) affecting Adobe Experience Manager (AEM) versions 6.5.23.0 and earlier. This vulnerability allows a low-privileged attacker to bypass security controls and gain unauthorized write access to the system. The flaw lies in improper enforcement of authorization checks, which means that certain security features designed to restrict access to sensitive operations or data can be circumvented. Exploitation requires network access (AV:N) and low privileges (PR:L), but does not require user interaction (UI:N). The vulnerability impacts the integrity of the system by allowing unauthorized modifications, but does not directly affect confidentiality or availability. The CVSS v3.1 base score is 6.5, indicating a medium severity level. No known exploits are currently reported in the wild, and no patches have been linked yet. Adobe Experience Manager is a widely used enterprise content management system, often deployed in large organizations for managing digital assets and web content. An attacker exploiting this vulnerability could potentially alter content, configurations, or other critical data, leading to defacement, misinformation, or further compromise of the environment.

For European organizations, the impact of this vulnerability can be significant, especially for those relying heavily on Adobe Experience Manager for their digital presence and content management. Unauthorized write access could lead to website defacement, injection of malicious content, or unauthorized changes to business-critical information. This could damage brand reputation, lead to regulatory non-compliance (e.g., GDPR if personal data is indirectly affected), and disrupt business operations. Additionally, attackers might leverage this foothold to move laterally within the network or escalate privileges, increasing the risk of broader compromise. Organizations in sectors such as government, finance, healthcare, and media, which often use AEM for public-facing and internal portals, are particularly at risk. The medium severity rating suggests that while the vulnerability is serious, exploitation requires some level of access and does not directly compromise confidentiality or availability, somewhat limiting the immediate impact but still posing a substantial threat to integrity.

Given the absence of an official patch link, European organizations should take proactive steps to mitigate risk. First, conduct a thorough audit of current AEM deployments to identify affected versions (6.5.23.0 and earlier). Restrict network access to AEM instances to trusted IPs and implement strict network segmentation to limit exposure. Employ robust access controls and monitor for unusual write operations or configuration changes within AEM. Enable detailed logging and integrate logs with a Security Information and Event Management (SIEM) system to detect potential exploitation attempts. Consider deploying Web Application Firewalls (WAFs) with custom rules to block suspicious requests targeting AEM endpoints. Until a patch is available, apply compensating controls such as increased monitoring, temporary disabling of non-essential write functionalities, and enforcing multi-factor authentication for all users with write privileges. Engage with Adobe support for updates and apply patches promptly once released. Finally, conduct employee awareness training to recognize signs of compromise related to content management systems.
