CVE-2025-11279 is a CSV Injection vulnerability identified in Axosoft Scrum and Bug Tracking version 22.1.1.11545. The vulnerability stems from insufficient validation or sanitization of the 'Title' parameter in the Add Work Item Page component. When a user inputs specially crafted content into the Title field, this content can be embedded into CSV exports without proper escaping or neutralization. Since spreadsheet applications like Microsoft Excel or LibreOffice Calc interpret certain leading characters (e.g., '=', '+', '-', '@') as formulas, an attacker can inject malicious formulas that execute when the CSV is opened. This can lead to arbitrary code execution, data exfiltration, or manipulation of spreadsheet data. The attack vector is remote and does not require authentication, but successful exploitation depends on a user opening the malicious CSV file, thus requiring user interaction. The vendor was notified early but has not issued a patch or response, leaving the vulnerability unmitigated. The CVSS 4.0 score of 5.1 reflects medium severity, considering the ease of exploitation (no authentication), the need for user interaction, and the limited impact on confidentiality, integrity, and availability. No known exploits are currently active in the wild, but public exploit code is available, increasing the risk of exploitation. This vulnerability highlights the risks of improper input handling in web applications that export data to CSV format, especially in project management and bug tracking tools widely used in software development environments.

For European organizations, the impact of CVE-2025-11279 can be significant in environments where Axosoft Scrum and Bug Tracking is used extensively for managing software projects and bug tracking. Exploitation could lead to the execution of malicious code on users' machines when they open exported CSV files, potentially compromising sensitive project data or enabling lateral movement within corporate networks. This could result in data integrity issues, unauthorized data disclosure, or disruption of development workflows. Since the attack requires user interaction, social engineering tactics may be employed to increase success rates. The lack of a vendor patch prolongs exposure, increasing the window for attackers to exploit the vulnerability. Organizations handling sensitive intellectual property or regulated data may face compliance risks if such an attack leads to data breaches. Additionally, the medium severity rating suggests that while the vulnerability is not critical, it can still cause meaningful operational and security impacts if leveraged effectively.

1. Implement input sanitization and validation on the 'Title' field to neutralize any characters that can trigger formula execution in CSV exports, such as prefixing potentially dangerous characters with a single quote or removing them entirely. 2. Educate users to be cautious when opening CSV files from untrusted or unexpected sources, emphasizing the risks of CSV Injection. 3. Use alternative export formats that do not interpret formulas, such as exporting to plain text or PDF, where feasible. 4. Employ endpoint security solutions that can detect and block suspicious macro or formula execution within spreadsheet applications. 5. Monitor logs and user activity for unusual access patterns or repeated export/download actions that could indicate exploitation attempts. 6. Engage with the vendor for updates or patches and consider temporary workarounds such as disabling CSV export functionality until a fix is available. 7. Apply network segmentation and least privilege principles to limit the potential impact of compromised user accounts. 8. Regularly update and patch spreadsheet applications to benefit from any built-in protections against formula injection attacks.
