CVE-2025-45854 is a critical security vulnerability identified in JEHC-BPM version 2.0.1, a business process management software developed by JEHc. The vulnerability is classified under CWE-862 (Missing Authorization) and CWE-434 (Unrestricted Upload of File with Dangerous Type), indicating a failure in enforcing proper authorization controls. Specifically, the issue resides in the /server/executeExec endpoint, which improperly handles the execParams parameter, allowing unauthenticated remote attackers to execute arbitrary code on the affected system. This means that an attacker can send crafted requests to this endpoint without any authentication or user interaction and trigger execution of malicious commands or code. The vulnerability has a CVSS v3.1 base score of 10.0, the highest possible severity rating, reflecting its critical nature. The CVSS vector (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H) indicates that the attack can be performed remotely over the network with low attack complexity, requires no privileges or user interaction, and results in complete compromise of confidentiality, integrity, and availability. The scope is changed, meaning the vulnerability affects resources beyond the initially vulnerable component. Although no known exploits in the wild have been reported yet, the criticality and ease of exploitation make this a significant threat. The lack of available patches at the time of publication further exacerbates the risk. This vulnerability could allow attackers to gain full control over systems running JEHC-BPM 2.0.1, potentially leading to data theft, disruption of business processes, deployment of ransomware, or use of the compromised system as a foothold for further attacks within a network.

For European organizations using JEHC-BPM 2.0.1, this vulnerability poses a severe risk. JEHC-BPM is likely used in enterprise environments to automate and manage critical business workflows, so exploitation could disrupt essential operations, cause data breaches involving sensitive personal or corporate information, and damage organizational reputation. The ability to execute arbitrary code remotely without authentication means attackers can bypass perimeter defenses and gain persistent access. This could lead to widespread operational downtime, regulatory non-compliance (especially under GDPR due to potential data exposure), financial losses, and legal consequences. Additionally, attackers could leverage compromised systems to pivot to other internal resources, amplifying the impact. The criticality of this vulnerability demands immediate attention from affected organizations to prevent potential large-scale incidents.

Given the absence of an official patch at the time of disclosure, European organizations should implement immediate compensating controls. These include: 1) Restricting network access to the /server/executeExec endpoint by applying strict firewall rules or network segmentation to limit exposure only to trusted management networks. 2) Deploying Web Application Firewalls (WAFs) with custom rules to detect and block suspicious execParams payloads or unusual requests targeting this endpoint. 3) Monitoring logs and network traffic for anomalous activity related to JEHC-BPM, especially any attempts to access /server/executeExec. 4) Conducting thorough inventory and asset management to identify all instances of JEHC-BPM 2.0.1 in the environment. 5) Preparing for rapid patch deployment once an official fix is released by JEHc. 6) Implementing strict access controls and multi-factor authentication for administrative interfaces to reduce risk of lateral movement. 7) Educating IT and security teams about this vulnerability to ensure prompt detection and response. These targeted measures go beyond generic advice by focusing on the specific vulnerable endpoint and the nature of the exploit vector.
