CVE-2026-1325 is a vulnerability found in the Sangfor Operation and Maintenance Security Management System, specifically affecting versions 3.0.0 through 3.0.12. The flaw resides in the password recovery functionality within the edit_pwd_mall endpoint (/fort/login/edit_pwd_mall). By manipulating the 'flag' parameter, an attacker can weaken or bypass the intended password recovery process. This manipulation allows remote attackers to reset or recover user passwords without proper authorization, as the vulnerability requires no authentication or user interaction. The weakness stems from insufficient validation or control over the 'flag' argument, which is critical in the password reset workflow. The vulnerability is remotely exploitable over the network, increasing the attack surface. Despite early notification, the vendor has not issued any patches or advisories, and a public exploit has been released, increasing the risk of exploitation. The CVSS 4.0 vector (AV:N/AC:L/AT:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:P) indicates network attack vector, low complexity, no privileges or user interaction required, no scope change, and partial impact on confidentiality and integrity. This vulnerability could lead to unauthorized access to administrative or user accounts, potentially compromising system integrity and confidentiality of managed assets.

For European organizations, this vulnerability poses a significant risk, especially for those relying on Sangfor's Operation and Maintenance Security Management System for critical infrastructure or security management. Exploitation could lead to unauthorized password resets, allowing attackers to gain access to sensitive management consoles or operational controls. This could result in unauthorized changes to security configurations, exposure of sensitive operational data, or disruption of maintenance activities. Given the lack of vendor response and patches, organizations face an elevated risk of exploitation, particularly if the system is exposed to untrusted networks. The medium severity score reflects a balance between ease of exploitation and limited impact scope; however, in environments where this system controls critical security functions, the impact could be more severe. European entities involved in sectors such as telecommunications, energy, or government infrastructure that deploy Sangfor products are particularly vulnerable. The public availability of exploits increases the likelihood of opportunistic attacks, potentially leading to data breaches or operational disruptions.

Organizations should immediately audit their deployment of Sangfor Operation and Maintenance Security Management System to identify affected versions (3.0.0 to 3.0.12). As no official patches are available, mitigations include restricting network access to the management interface, ideally isolating it within trusted internal networks or VPNs. Implement strict firewall rules to limit access to the password recovery endpoint (/fort/login/edit_pwd_mall) only to authorized IP addresses. Monitor logs for suspicious password recovery attempts or anomalous use of the 'flag' parameter. Employ multi-factor authentication (MFA) on all accounts where possible to reduce the impact of compromised credentials. Consider deploying web application firewalls (WAFs) with custom rules to detect and block exploitation attempts targeting the vulnerable parameter. Engage with Sangfor support channels for updates or potential workarounds. Plan for rapid patching once a vendor fix is released. Additionally, conduct user awareness training to recognize phishing or social engineering attempts that could leverage this vulnerability. Finally, maintain comprehensive backups and incident response plans to mitigate potential breaches.
