CVE-2025-36016 is a security vulnerability classified as an Open Redirect (CWE-601) found in IBM Process Mining versions 2.0.1 and 2.0.1 IF001. This vulnerability allows a remote attacker to craft malicious URLs that appear to originate from a trusted IBM Process Mining domain but redirect users to untrusted, potentially malicious websites. The attack vector involves persuading victims to click on a specially crafted link, which exploits the application's improper validation of URL redirection parameters. When a user follows such a link, they are redirected to an attacker-controlled site, which can be used for phishing attacks, credential harvesting, or further exploitation. The vulnerability has a CVSS 3.1 base score of 6.8, indicating a medium severity level. The vector metrics specify that the attack can be performed remotely over the network (AV:N) with low attack complexity (AC:L), requires privileges (PR:L), and user interaction (UI:R). The scope is changed (S:C), meaning the vulnerability affects resources beyond the initially vulnerable component. The impact affects integrity (I:H) but not confidentiality or availability. No known exploits have been reported in the wild yet, and no patches are currently linked, indicating that mitigation may require vendor updates or configuration changes. Open Redirect vulnerabilities are commonly leveraged in social engineering attacks to bypass user suspicion by making malicious URLs appear legitimate, increasing the likelihood of successful phishing campaigns.

For European organizations using IBM Process Mining 2.0.1 or 2.0.1 IF001, this vulnerability poses a significant risk primarily through social engineering and phishing attacks. Attackers can exploit the open redirect to craft URLs that appear to be from a trusted internal or partner source, increasing the chance that employees or stakeholders will click on malicious links. This can lead to credential theft, unauthorized access to sensitive business process data, or further compromise of internal systems if the attacker uses the redirect as a stepping stone for more advanced attacks. Given the importance of process mining in operational efficiency and compliance, any compromise could disrupt business processes or expose sensitive operational insights. The requirement for user interaction and privileges limits the attack surface somewhat, but the medium severity rating indicates a notable risk that should be addressed promptly. Additionally, the changed scope implies that the impact could extend beyond the IBM Process Mining application itself, potentially affecting integrated systems or services.

To mitigate this vulnerability, European organizations should first verify if they are running the affected IBM Process Mining versions (2.0.1 or 2.0.1 IF001). Until an official patch is released, organizations can implement the following measures: 1) Review and restrict URL redirection parameters within the application configuration or web server rules to ensure only trusted domains are allowed for redirects. 2) Employ web application firewalls (WAFs) with custom rules to detect and block suspicious redirect patterns targeting IBM Process Mining endpoints. 3) Enhance user awareness training focused on recognizing phishing attempts, especially those involving URLs that appear legitimate but redirect externally. 4) Monitor logs for unusual redirect activities or spikes in user redirection requests. 5) Limit user privileges to the minimum necessary to reduce the attacker's ability to exploit the vulnerability. 6) Coordinate with IBM support to obtain patches or updates as soon as they become available and plan timely deployment. 7) Consider implementing multi-factor authentication (MFA) on systems accessed via IBM Process Mining to reduce the impact of credential compromise.
