CVE-2025-9715 is a cross-site scripting (XSS) vulnerability identified in the O2OA platform, specifically affecting versions up to 10.0-410. The vulnerability resides in an unspecified function within the /x_cms_assemble_control/jaxrs/script file, which is part of the Personal Profile Page component. The flaw arises from improper sanitization or validation of user-supplied input in the parameters 'name', 'alias', and 'description'. An attacker can remotely manipulate these parameters to inject malicious scripts that execute in the context of the victim's browser. This type of vulnerability can be exploited without authentication and does not require user privileges, but it does require user interaction (e.g., the victim visiting a crafted URL or page). The vendor has acknowledged the issue and indicated that a fix will be included in a forthcoming version. The CVSS v4.0 base score is 5.1, categorizing it as a medium severity vulnerability. The vector indicates network attack vector, low attack complexity, no privileges required, but user interaction is necessary. The impact primarily affects confidentiality and integrity at a limited level, with no direct impact on availability. No known exploits are currently active in the wild, but public exploit code has been released, increasing the risk of exploitation.

For European organizations using O2OA, this vulnerability poses a risk of client-side attacks that could lead to session hijacking, credential theft, or unauthorized actions performed on behalf of users. Since the vulnerability affects the Personal Profile Page, attackers might target user profile management functions to inject malicious scripts. This could compromise user trust and lead to data leakage or unauthorized access to sensitive information. Organizations in sectors with stringent data protection requirements, such as finance, healthcare, and government, could face compliance issues if user data is compromised. Additionally, the presence of public exploit code increases the likelihood of opportunistic attacks, especially against organizations that have not yet applied patches or mitigations. The medium severity rating suggests that while the vulnerability is not critical, it still requires timely attention to prevent exploitation that could escalate into more severe breaches.

European organizations should prioritize updating O2OA to the vendor's forthcoming patched version once available. In the interim, applying strict input validation and output encoding on the affected parameters ('name', 'alias', 'description') can mitigate the risk. Web Application Firewalls (WAFs) should be configured to detect and block typical XSS payloads targeting these parameters. Organizations should also conduct thorough code reviews and penetration testing focused on the Personal Profile Page to identify and remediate similar injection points. User education about phishing and suspicious links can reduce the risk of successful exploitation. Monitoring web server logs for unusual requests to /x_cms_assemble_control/jaxrs/script and anomalous user behavior can help detect attempted attacks early. Finally, implementing Content Security Policy (CSP) headers can limit the impact of injected scripts by restricting the sources from which scripts can be executed.
