CVE-2025-57906 is a medium-severity vulnerability classified as CWE-79, indicating an Improper Neutralization of Input During Web Page Generation, commonly known as Cross-site Scripting (XSS). This vulnerability affects the epeken Epeken All Kurir product, specifically versions up to 2.0.2. The issue allows an attacker to inject malicious scripts that are stored persistently on the vulnerable web application. When other users access the affected pages, the malicious scripts execute in their browsers, potentially leading to session hijacking, credential theft, or unauthorized actions performed on behalf of the victim. The CVSS 3.1 vector (AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:L) indicates that the attack can be performed remotely over the network with low attack complexity but requires high privileges and user interaction. The scope is changed, meaning the vulnerability affects resources beyond the initially vulnerable component. The impact on confidentiality, integrity, and availability is low to medium, as the attacker can partially compromise user data and application behavior but not fully control the system or cause significant downtime. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability arises from insufficient input sanitization or output encoding during web page generation, allowing malicious payloads to be stored and later executed in users' browsers.

For European organizations using Epeken All Kurir, this vulnerability poses a risk primarily to the confidentiality and integrity of user data and session information. Attackers exploiting this flaw could hijack user sessions, steal sensitive information, or perform unauthorized actions within the application context. This could lead to data breaches, reputational damage, and potential regulatory non-compliance under GDPR if personal data is exposed. The requirement for high privileges to exploit reduces the risk from external attackers but elevates concern for insider threats or compromised accounts. Additionally, user interaction is necessary, which may limit automated mass exploitation but does not eliminate targeted attacks. Organizations relying on this software for logistics or courier management could face operational disruptions if attackers manipulate data or user workflows. The medium severity suggests a moderate risk level, but the potential for chained attacks or further exploitation remains a concern.

European organizations should implement the following specific mitigations: 1) Immediately audit and restrict user privileges within Epeken All Kurir to minimize the number of users with high-level access, reducing the attack surface. 2) Employ strict input validation and output encoding on all user-supplied data fields, especially those that are stored and later rendered in web pages. 3) Monitor application logs for unusual activities indicative of attempted XSS exploitation, such as suspicious script injections or repeated failed input sanitization attempts. 4) Educate users about the risks of interacting with unexpected or suspicious content within the application to reduce successful exploitation via social engineering. 5) Engage with the vendor or community to obtain patches or updates addressing this vulnerability as soon as they become available. 6) Consider deploying Web Application Firewalls (WAFs) with custom rules to detect and block XSS payloads targeting Epeken All Kurir. 7) Conduct regular security assessments and penetration testing focusing on stored XSS vectors within the application environment.
