CVE-2025-53264: CWE-352 Cross-Site Request Forgery (CSRF) in Konrád Koller ONet Regenerate Thumbnails
Cross-Site Request Forgery (CSRF) vulnerability in Konrád Koller ONet Regenerate Thumbnails allows Cross Site Request Forgery. This issue affects ONet Regenerate Thumbnails: from n/a through 1.5.
AI Analysis
Technical Summary
CVE-2025-53264 is a Cross-Site Request Forgery (CSRF) vulnerability identified in the ONet Regenerate Thumbnails plugin developed by Konrád Koller. This vulnerability affects versions up to 1.5 of the plugin. CSRF vulnerabilities allow an attacker to trick an authenticated user into submitting a forged HTTP request to a web application, causing the user to perform unwanted actions without their consent. In this case, the vulnerability could allow an attacker to initiate the regeneration of thumbnails on the affected system by exploiting the lack of proper CSRF protections. The CVSS 3.1 base score is 4.3, indicating a medium severity level. The vector string (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N) shows that the attack can be performed remotely over the network without privileges but requires user interaction (such as clicking a malicious link). The impact is limited to integrity, as the attacker can cause unauthorized changes (thumbnail regeneration) but does not affect confidentiality or availability. There are no known exploits in the wild at the time of publication, and no patches have been linked yet. The vulnerability is classified under CWE-352, which is a common web security weakness related to CSRF attacks. The vulnerability is relevant to web applications using the ONet Regenerate Thumbnails plugin, which is typically used in content management systems to regenerate image thumbnails.
Potential Impact
For European organizations using the ONet Regenerate Thumbnails plugin, this vulnerability poses a moderate risk. While the direct impact is limited to the integrity of thumbnail images, unauthorized regeneration could disrupt website appearance or functionality, potentially affecting user experience and brand reputation. In environments where image thumbnails are critical for e-commerce, media, or publishing platforms, this could lead to operational disruptions or customer dissatisfaction. Since the vulnerability requires user interaction, phishing or social engineering campaigns could be used to exploit it. However, the lack of confidentiality or availability impact reduces the risk of data breaches or service outages. Nonetheless, attackers could use this vulnerability as part of a broader attack chain to undermine trust or prepare for more damaging exploits. European organizations with public-facing websites using this plugin should consider the risk in the context of their threat landscape and user base.
Mitigation Recommendations
To mitigate this vulnerability, organizations should implement the following specific measures: 1) Apply any available patches or updates from the vendor as soon as they are released. Since no patch links are currently available, monitor vendor communications closely. 2) Implement anti-CSRF tokens in all forms and state-changing requests within the ONet Regenerate Thumbnails plugin to ensure requests are legitimate and originate from authorized users. 3) Employ web application firewalls (WAFs) with rules designed to detect and block CSRF attack patterns targeting this plugin. 4) Educate users and administrators about the risks of phishing and social engineering attacks that could trigger CSRF exploits, emphasizing cautious behavior with unsolicited links. 5) Restrict access to the plugin’s functionality to authenticated and authorized users only, and consider additional authentication factors to reduce the risk of unauthorized actions. 6) Conduct regular security assessments and penetration tests focusing on web application vulnerabilities including CSRF to identify and remediate similar issues proactively.
