CVE-2025-49979 is a security vulnerability classified under CWE-862, indicating a Missing Authorization issue in the slui Media Hygiene product, versions up to 4.0.1. This vulnerability arises due to incorrectly configured access control security levels, allowing users with limited privileges (requiring only low-level privileges) to perform actions or access resources that should be restricted. The vulnerability does not require user interaction and can be exploited remotely over the network (AV:N), with low attack complexity (AC:L). The CVSS 3.1 base score is 4.3, reflecting a medium severity level. The impact primarily affects confidentiality, with limited or no impact on integrity or availability. Specifically, an attacker with some level of authenticated access (PR:L) can gain unauthorized access to certain data or functionalities within Media Hygiene, potentially exposing sensitive information. No known exploits are currently reported in the wild, and no patches have been published yet. The vulnerability affects all versions up to 4.0.1, though the exact earliest affected version is unspecified (noted as 'n/a'). The lack of proper authorization checks indicates a design or implementation flaw in the access control mechanisms of the Media Hygiene product, which could be leveraged by insiders or attackers who have gained low-level credentials to escalate their access privileges improperly.

For European organizations using slui Media Hygiene, this vulnerability could lead to unauthorized disclosure of sensitive media hygiene data or related operational information, potentially undermining privacy and compliance with regulations such as GDPR. Although the impact on integrity and availability is negligible, unauthorized access to confidential data could facilitate further attacks or insider threats. Organizations in sectors handling sensitive media content, digital rights management, or media compliance monitoring may be particularly at risk. The medium severity suggests that while the vulnerability is not critical, it still poses a meaningful risk, especially if combined with other vulnerabilities or used as a foothold for lateral movement within networks. The absence of known exploits reduces immediate risk but should not lead to complacency, as attackers may develop exploits once the vulnerability becomes widely known.

1. Implement strict access control policies and review current privilege assignments within Media Hygiene to ensure least privilege principles are enforced. 2. Conduct a thorough audit of Media Hygiene user roles and permissions to identify and remediate any misconfigurations or excessive privileges. 3. Monitor logs for unusual access patterns or attempts to access unauthorized resources within Media Hygiene. 4. Until an official patch is released, consider isolating the Media Hygiene system from untrusted networks or restricting access to trusted administrators only. 5. Engage with the vendor for timely updates and patches, and plan for rapid deployment once available. 6. Employ compensating controls such as network segmentation, multi-factor authentication for all users with access to Media Hygiene, and enhanced monitoring to detect potential exploitation attempts. 7. Train staff on the risks associated with privilege misuse and the importance of safeguarding credentials to reduce insider threat risks.
