CVE-2025-11279 is a CSV Injection vulnerability identified in Axosoft Scrum and Bug Tracking version 22.1.1.11545. The vulnerability arises from improper handling of user-supplied input in the 'Title' argument on the Add Work Item Page component. Specifically, the application fails to sanitize or validate input that is later exported or processed as CSV data. This flaw allows an attacker to inject malicious formulas or commands into CSV files generated by the application. When a user opens the crafted CSV file in spreadsheet software such as Microsoft Excel or LibreOffice Calc, the embedded malicious formulas can execute, potentially leading to data manipulation, information disclosure, or further code execution within the context of the spreadsheet application. The attack vector is remote and does not require authentication, although user interaction is necessary to open the malicious CSV file. The CVSS 4.0 base score is 5.1 (medium severity), reflecting network attack vector, low attack complexity, no privileges required, but requiring user interaction and limited impact on confidentiality, integrity, and availability. The vendor has not responded to the disclosure, and no patches or mitigations have been published yet. The exploit is public, increasing the risk of exploitation. CSV Injection vulnerabilities are often overlooked but can lead to significant downstream impacts, especially in environments where exported data is widely shared and trusted. Given that Axosoft Scrum and Bug Tracking is used for project management and bug tracking, the injection could be used to manipulate data or execute malicious commands within the spreadsheet environment, potentially impacting decision-making and data integrity.

For European organizations using Axosoft Scrum and Bug Tracking 22.1.1.11545, this vulnerability poses a moderate risk. The primary impact is on data integrity and confidentiality, as malicious CSV payloads can execute arbitrary spreadsheet formulas that might exfiltrate data or alter data presentation. This can lead to misinformation, erroneous project tracking, or unauthorized data disclosure. Since the vulnerability requires user interaction (opening a malicious CSV), social engineering or phishing campaigns could be used to deliver the payload. European organizations with collaborative workflows that export and share CSV reports internally or externally are particularly at risk. Additionally, sectors with strict data protection regulations such as GDPR may face compliance risks if sensitive data is leaked or manipulated. The lack of vendor response and absence of patches increases exposure time. However, the vulnerability does not directly allow remote code execution on the server or network compromise, limiting its impact to the client environment where the CSV is opened. Still, the risk of lateral movement or further exploitation via malicious macros or formulas embedded in CSV files should not be underestimated.

1. Immediate mitigation should include educating users about the risks of opening CSV files from untrusted or unexpected sources, especially those exported from Axosoft Scrum and Bug Tracking. 2. Implement strict input validation and sanitization on the 'Title' field to neutralize characters that trigger formula execution in CSV files (e.g., '=', '+', '-', '@'). 3. Where possible, configure spreadsheet software to disable automatic formula execution or enable CSV import warnings. 4. Use alternative export formats that do not support formula execution, such as plain text or PDF, until a vendor patch is available. 5. Monitor and restrict the sharing of exported CSV files to trusted recipients only. 6. Apply network-level controls to detect and block phishing attempts that might deliver malicious CSV files. 7. Engage with Axosoft for patch timelines and consider temporary migration to unaffected versions or alternative tools if feasible. 8. Implement Data Loss Prevention (DLP) solutions to detect and prevent sensitive data leakage through CSV exports. These steps go beyond generic advice by focusing on both technical controls and user awareness tailored to the specific vulnerability context.
