CVE-2025-55371 is a security vulnerability identified in the jshERP software version 3.5, specifically within the /controller/PersonController.java component. The vulnerability arises from incorrect access control implementation in the getAllList method. This flaw allows unauthorized attackers to bypass intended access restrictions and retrieve all information related to the handler, which likely includes sensitive personal or organizational data managed by the ERP system. Since the vulnerability is in a controller component, it suggests that the issue is at the application logic level, where insufficient authorization checks fail to prevent unauthorized data access. The lack of a CVSS score and absence of known exploits in the wild indicate that this vulnerability is newly disclosed and may not yet have been widely exploited. However, the nature of the flaw—unauthorized data access—poses a significant risk to confidentiality and potentially to the integrity of the data if combined with other vulnerabilities or attack vectors. The vulnerability does not specify affected versions beyond jshERP v3.5, and no patches or mitigations have been published yet, which increases the urgency for organizations using this software to assess their exposure and implement compensating controls.

For European organizations using jshERP v3.5, this vulnerability could lead to unauthorized disclosure of sensitive information managed within the ERP system. This may include personal data of employees, customers, or business-critical information, potentially violating GDPR and other data protection regulations. The exposure of handler information could facilitate further targeted attacks, social engineering, or fraud. The breach of confidentiality could damage organizational reputation, lead to regulatory fines, and disrupt business operations. Since ERP systems are central to many business processes, unauthorized data access could also impact operational integrity and trustworthiness of data. The lack of authentication requirements mentioned suggests that exploitation might be possible without valid credentials, increasing the risk profile. European organizations in sectors such as manufacturing, retail, and services that rely on jshERP for resource planning and management are particularly at risk.

Given the absence of official patches, European organizations should immediately conduct a thorough audit of their jshERP deployments to identify if version 3.5 is in use. If so, restrict network access to the ERP system to trusted internal networks and enforce strict firewall rules to limit exposure. Implement application-layer access controls or web application firewalls (WAFs) that can detect and block unauthorized attempts to invoke the getAllList method. Conduct code reviews or penetration testing to identify if similar access control issues exist in other parts of the application. Monitor logs for unusual access patterns or data retrieval attempts. Where possible, isolate the ERP system from internet-facing environments until a patch is available. Engage with the jshERP vendor or community to obtain updates or patches and apply them promptly once released. Additionally, ensure that data encryption at rest and in transit is enforced to mitigate data exposure risks.
