CVE-2025-0929

Comprehensive Technical Analysis of CVE-2025-0929

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-0929 Description: SQL injection vulnerability in TeamCal Neo, version 3.8.2. This could allow an attacker to retrieve, update, and delete all database information by injecting a malicious SQL statement via the ‘abs’ parameter in ‘/teamcal/src/index.php’. CVSS Score: 9.8

Severity Evaluation: The CVSS score of 9.8 indicates a critical vulnerability. This high score is due to the potential for complete database compromise, including unauthorized access to sensitive information, data manipulation, and data loss. The vulnerability's exploitability and the severe impact on data integrity and confidentiality contribute to its critical rating.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Direct SQL Injection: An attacker can craft a malicious SQL statement and inject it through the ‘abs’ parameter in the URL.
• Automated Tools: Attackers may use automated SQL injection tools to identify and exploit the vulnerability.
• Phishing: An attacker could trick a user into clicking a malicious link that exploits the vulnerability.

Exploitation Methods:

• Data Exfiltration: Retrieve sensitive information from the database.
• Data Manipulation: Modify database entries to disrupt operations or inject malicious content.
• Data Deletion: Delete critical database records, leading to data loss and service disruption.

3. Affected Systems and Software Versions

Affected Software:

• TeamCal Neo, version 3.8.2

Affected Systems:

• Any system running TeamCal Neo version 3.8.2, including web servers and database servers connected to the application.

4. Recommended Mitigation Strategies

Immediate Actions:

• Patching: Apply the latest security patch provided by the vendor to mitigate the vulnerability.
• Input Validation: Implement strict input validation and sanitization for the ‘abs’ parameter to prevent SQL injection.
• Parameterized Queries: Use parameterized queries or prepared statements to ensure that SQL commands are not directly executed from user input.

Long-Term Strategies:

• Regular Updates: Ensure that all software, including TeamCal Neo, is regularly updated to the latest versions.
• Security Audits: Conduct regular security audits and vulnerability assessments to identify and mitigate potential vulnerabilities.
• Web Application Firewalls (WAF): Deploy WAFs to monitor and block malicious SQL injection attempts.

5. Impact on Cybersecurity Landscape

Immediate Impact:

• Data Breaches: Organizations using TeamCal Neo version 3.8.2 are at high risk of data breaches, leading to potential financial and reputational damage.
