CVE-2025-57998 is a medium-severity Stored Cross-Site Scripting (XSS) vulnerability identified in the E-namad & Shamed Logo Manager software developed by Hamid Reza Yazdani. The vulnerability arises from improper neutralization of input during web page generation, classified under CWE-79. Specifically, the application fails to adequately sanitize or encode user-supplied input before rendering it in web pages, allowing malicious actors to inject and store executable scripts. When other users or administrators access the affected pages, these scripts execute in their browsers within the context of the vulnerable application. The CVSS 3.1 base score is 5.9, reflecting a network attack vector with low attack complexity but requiring high privileges and user interaction. The scope is changed, indicating that exploitation can affect components beyond the initially vulnerable module. The impact includes limited confidentiality, integrity, and availability losses, such as theft of session tokens, defacement, or redirection to malicious sites. No known exploits are currently reported in the wild, and no patches have been published yet. The affected versions include all versions up to 2.2, though the exact range is unspecified. Stored XSS is particularly dangerous because injected scripts persist on the server and affect multiple users, increasing the attack surface and potential damage. This vulnerability requires an authenticated user with high privileges to exploit, and user interaction is necessary to trigger the malicious payload. Given these factors, the vulnerability poses a moderate risk but should be addressed promptly to prevent escalation or chaining with other vulnerabilities.

For European organizations using E-namad & Shamed Logo Manager, this vulnerability could lead to unauthorized execution of scripts within the context of their web applications. Potential impacts include session hijacking, unauthorized actions performed on behalf of legitimate users, defacement of web content, and distribution of malware through the compromised interface. This can damage organizational reputation, lead to data breaches involving personal or sensitive information, and disrupt business operations. Since the vulnerability requires high privileges and user interaction, insider threats or compromised privileged accounts could be leveraged by attackers to exploit this flaw. Organizations in sectors with stringent data protection regulations, such as finance, healthcare, and government, may face compliance risks and legal consequences if exploited. Additionally, the persistence of stored XSS increases the risk of widespread impact across multiple users and systems. The lack of available patches means organizations must rely on interim mitigations to reduce exposure. Overall, the vulnerability could undermine trust in affected web services and lead to financial and operational losses if exploited.

1. Implement strict input validation and output encoding: Organizations should audit the E-namad & Shamed Logo Manager source code or configuration to ensure all user inputs are properly sanitized and encoded before rendering in web pages, especially in HTML, JavaScript, and attribute contexts. 2. Employ Content Security Policy (CSP): Deploy a robust CSP header to restrict the execution of unauthorized scripts and reduce the impact of potential XSS payloads. 3. Restrict privileges: Limit the number of users with high privileges required to exploit this vulnerability and enforce the principle of least privilege. 4. Monitor and log user inputs and application behavior to detect suspicious activities indicative of attempted exploitation. 5. Use web application firewalls (WAFs) with rules tailored to detect and block XSS attack patterns targeting this product. 6. Educate privileged users about phishing and social engineering risks to reduce the chance of user interaction enabling exploitation. 7. Coordinate with the vendor or community to obtain patches or updates as soon as they become available and apply them promptly. 8. Conduct regular security assessments and penetration testing focusing on XSS vulnerabilities within the affected application. These measures go beyond generic advice by focusing on privilege management, monitoring, and compensating controls in the absence of immediate patches.
