CVE-2025-13185 is a vulnerability identified in Bdtask's News365 product, versions 7.0.0 through 7.0.3. The flaw resides in the /admin/dashboard/profile endpoint, where the parameters profile_image and banner_image are susceptible to unrestricted file upload. This means that an attacker with authenticated high-level privileges can upload arbitrary files, including potentially malicious scripts or executables, without proper validation or sanitization. The vulnerability is remotely exploitable and does not require user interaction, but it does require the attacker to have high privilege authentication, such as an administrator account. The CVSS v4.0 score is 5.1 (medium severity), reflecting the moderate impact and the requirement for privileged access. The vulnerability could lead to server-side compromise, enabling attackers to execute arbitrary code, deface websites, or pivot within the network. Despite the exploit being publicly available, no confirmed active exploitation has been reported. The vendor was notified early but has not issued any patches or responses, leaving organizations reliant on their own mitigations. The lack of patch availability increases the urgency for organizations to implement compensating controls. This vulnerability highlights the risks associated with insufficient input validation in file upload functionalities, especially in administrative interfaces.

For European organizations, the impact of this vulnerability can be significant, particularly for those using Bdtask News365 in their content management or news publishing workflows. Successful exploitation could lead to unauthorized code execution on web servers, resulting in data breaches, defacement, or disruption of services. Confidential information stored or processed by the affected systems could be exposed or altered, undermining data integrity. Availability could also be impacted if attackers deploy ransomware or other destructive payloads. Given the administrative nature of the affected endpoint, attackers could gain persistent access or escalate privileges further within the network. This risk is heightened in sectors such as media, government, and enterprises relying on News365 for public-facing content. The public availability of exploit code increases the likelihood of opportunistic attacks, especially against organizations with weak internal controls or insufficient monitoring. The absence of vendor patches means European organizations must rely on internal security measures to mitigate risk, increasing operational burden and potential exposure.

Since no official patch is available, European organizations should implement the following specific mitigations: 1) Restrict file upload types strictly on the server side, allowing only safe image formats (e.g., JPEG, PNG) and rejecting all others. 2) Implement robust server-side validation and sanitization of uploaded files, including checking MIME types, file extensions, and scanning for embedded malicious code. 3) Employ web application firewalls (WAFs) with custom rules to detect and block suspicious upload attempts targeting the profile_image/banner_image parameters. 4) Enforce the principle of least privilege by limiting administrative access to trusted personnel and using multi-factor authentication to reduce risk of credential compromise. 5) Monitor logs and network traffic for unusual activity related to file uploads or administrative actions. 6) Consider isolating the News365 application environment to limit lateral movement in case of compromise. 7) Regularly back up critical data and test restoration procedures to mitigate impact of potential attacks. 8) Engage in active threat hunting for indicators of compromise related to this vulnerability. 9) If feasible, temporarily disable or restrict the vulnerable upload functionality until a vendor patch is released. 10) Maintain awareness of vendor communications for any future updates or patches.
