CVE-2025-9241 is a CSV Injection vulnerability identified in the elunez eladmin software versions 2.0 through 2.7, specifically affecting the exportUser function. CSV Injection, also known as Formula Injection, occurs when untrusted input is embedded into CSV files without proper sanitization or escaping. When these CSV files are opened in spreadsheet applications like Microsoft Excel or LibreOffice Calc, maliciously crafted cells can execute spreadsheet formulas or commands, potentially leading to arbitrary code execution or data manipulation on the client side. In this case, the vulnerability allows an attacker to remotely inject malicious content into exported CSV files generated by the exportUser function. The vulnerability does not require user interaction or authentication, making it easier to exploit remotely. The CVSS 4.0 base score is 5.3 (medium severity), reflecting the network attack vector, low complexity, no privileges required, no user interaction, and limited impact on confidentiality, integrity, and availability. Although no known exploits are currently observed in the wild, the exploit code has been publicly disclosed, increasing the risk of exploitation. The vulnerability arises from insufficient input validation or sanitization of user data that is exported to CSV format, allowing attackers to craft payloads that execute when the CSV is opened in vulnerable spreadsheet software. This can lead to unauthorized commands running on the client machine, data leakage, or manipulation of spreadsheet content. Since eladmin is an administrative platform, the exportUser function likely handles sensitive user data, increasing the risk of exposure or manipulation if exploited.

For European organizations using elunez eladmin versions 2.0 to 2.7, this vulnerability poses a moderate risk. The primary impact is on confidentiality and integrity of user data exported via CSV files. Attackers can craft malicious CSV exports that, when opened by administrators or analysts in spreadsheet applications, could execute arbitrary formulas or commands, potentially leading to credential theft, lateral movement, or data manipulation. This could compromise sensitive user information or administrative controls. The vulnerability does not directly affect availability but could indirectly disrupt operations if trusted CSV files are weaponized. European organizations in sectors such as government, finance, healthcare, and critical infrastructure that rely on eladmin for user management are particularly at risk. The ease of remote exploitation without authentication increases the threat surface. However, the requirement that the victim opens the malicious CSV file limits the attack vector to social engineering or phishing scenarios. The public availability of exploit code increases the likelihood of opportunistic attacks. Overall, the impact is moderate but significant enough to warrant prompt mitigation to prevent data breaches or administrative compromise.

1. Immediate upgrade: Organizations should upgrade elunez eladmin to a version patched against CVE-2025-9241 once available. If no patch is currently released, contact the vendor for guidance or apply any recommended workarounds. 2. Input sanitization: Implement strict input validation and sanitization on all user inputs that are exported to CSV files. Escape or prefix potentially dangerous characters such as '=', '+', '-', '@' in CSV cells to prevent formula execution. 3. CSV handling policies: Train users and administrators to handle CSV files cautiously. Avoid opening CSV files from untrusted sources directly in spreadsheet applications. Use text editors or import CSV data with formula execution disabled. 4. Use safer export formats: Where possible, export user data in formats that do not support formula execution, such as plain text or JSON, or use CSV export tools that automatically sanitize inputs. 5. Network controls: Monitor and restrict access to the exportUser function to trusted users and networks to reduce exposure. 6. Logging and monitoring: Enable detailed logging of export operations and monitor for unusual CSV export activity that could indicate exploitation attempts. 7. User awareness: Educate staff about the risks of CSV injection and phishing attacks that could deliver malicious CSV files.
