CVE-2025-68558 is a vulnerability identified in the averta Depicter Slider plugin, specifically affecting versions up to 4.0.4. The core issue is a missing authorization mechanism, which means that the plugin fails to properly enforce access control security levels. This misconfiguration allows an unauthenticated remote attacker to perform actions that should be restricted, potentially modifying content or disrupting the slider's functionality. The vulnerability does not impact confidentiality but affects integrity and availability, as unauthorized changes or denial of service could occur. The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:L) indicates that the attack can be performed over the network with low attack complexity, no privileges, and no user interaction required. Despite the absence of known exploits in the wild and no available patches at the time of publication, the vulnerability poses a tangible risk to affected systems. The averta Depicter Slider is commonly used in web content management systems to create image sliders, so compromised instances could lead to defacement or functional disruption of websites. Organizations should prioritize identifying instances of this plugin and verifying their version to assess exposure.

For European organizations, the impact centers on potential unauthorized modifications to web content and service disruptions caused by exploitation of this missing authorization vulnerability. While confidentiality is not directly affected, integrity breaches could lead to defacement, misinformation, or unauthorized content injection, damaging brand reputation and user trust. Availability impacts could result in slider components failing to load or function, degrading user experience and possibly affecting business operations reliant on web presence. Industries with high reliance on digital marketing, e-commerce, or public-facing informational websites are particularly vulnerable. Additionally, organizations subject to strict regulatory requirements around data integrity and service availability (e.g., financial services, healthcare) may face compliance risks. The lack of authentication or user interaction requirements means attackers can exploit this vulnerability remotely and at scale, increasing the threat surface for European entities.

1. Immediately inventory all web assets to identify deployments of averta Depicter Slider and confirm their versions. 2. Apply any available patches or updates from the vendor as soon as they are released; monitor vendor communications closely. 3. In the absence of patches, implement compensating controls such as web application firewalls (WAFs) with rules to restrict unauthorized access to slider management endpoints. 4. Review and tighten access control configurations on web servers and CMS platforms hosting the plugin to ensure only authorized users can modify slider content. 5. Monitor web server logs and application logs for anomalous requests targeting slider endpoints or unusual modification patterns. 6. Conduct penetration testing focused on access control weaknesses in web applications using this plugin. 7. Educate web administrators and developers about the risks of missing authorization and enforce secure coding and configuration practices. 8. Consider temporary removal or disabling of the plugin if immediate patching or mitigation is not feasible and the risk is deemed high.
