CVE-2025-31375 identifies a Cross-Site Request Forgery (CSRF) vulnerability in the bhoogterp Scheduled product, specifically affecting versions up to 1.0. CSRF vulnerabilities allow attackers to trick authenticated users into submitting unwanted requests to a web application, exploiting the user's credentials and session. In this case, the CSRF flaw enables an attacker to perform unauthorized scheduling actions that result in Stored Cross-Site Scripting (XSS). Stored XSS occurs when malicious scripts are permanently stored on the target server, such as in a database or scheduled task, and later executed in the context of users' browsers. This combination significantly increases the attack surface, as CSRF can be used to inject persistent malicious scripts that affect multiple users. The vulnerability is due to insufficient validation or lack of anti-CSRF tokens in the scheduling functionality of the bhoogterp Scheduled product. No patches or fixes are currently linked, and no known exploits have been reported in the wild as of the publication date. The vulnerability was reserved in late March 2025 and published in April 2025. The absence of a CVSS score requires an independent severity assessment based on the potential impact on confidentiality, integrity, and availability, as well as ease of exploitation and scope.

The impact of CVE-2025-31375 can be significant for organizations using the bhoogterp Scheduled product. Successful exploitation allows attackers to perform unauthorized actions on behalf of legitimate users, potentially injecting persistent malicious scripts via Stored XSS. This can lead to session hijacking, credential theft, unauthorized data access, and further compromise of internal systems. The Stored XSS aspect means that multiple users accessing the scheduled data could be affected, amplifying the damage. Additionally, the CSRF vulnerability undermines the integrity of the scheduling system, potentially disrupting business processes reliant on scheduled tasks. Organizations with sensitive or critical scheduling operations may face operational disruptions or data breaches. Since no authentication bypass is indicated, attackers need an authenticated user session or to trick users into visiting malicious sites, which is feasible in many environments. The lack of known exploits in the wild suggests limited current exploitation but does not reduce the potential risk if weaponized. Overall, the threat poses a medium to high risk depending on the deployment context and user base.

To mitigate CVE-2025-31375, organizations should implement multiple layers of defense: 1) Apply patches or updates from the vendor once available; monitor bhoogterp communications for fixes. 2) Implement anti-CSRF tokens in all state-changing requests within the Scheduled product to ensure requests originate from legitimate users. 3) Enforce strict input validation and output encoding to prevent Stored XSS payloads from being injected or executed. 4) Restrict scheduling functionality access to authorized users only, using role-based access controls and least privilege principles. 5) Employ Content Security Policy (CSP) headers to limit the impact of any injected scripts. 6) Educate users about the risks of clicking untrusted links to reduce CSRF attack vectors. 7) Monitor logs and network traffic for unusual scheduling requests or script injections. 8) Consider isolating or sandboxing the Scheduled application environment to limit lateral movement if compromised. These steps go beyond generic advice by focusing on the specific vulnerability vectors and the nature of the product.
