CVE-2025-22954

Comprehensive Technical Analysis of CVE-2025-22954

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-22954 Description: The vulnerability resides in the GetLateOrMissingIssues function within the C4/Serials.pm module of Koha, an open-source Integrated Library System (ILS). Specifically, the /serials/lateissues-export.pl script is susceptible to SQL Injection attacks via the supplierid or serialid parameters. CVSS Score: 10

Severity Evaluation:

• Criticality: The CVSS score of 10 indicates a critical vulnerability. This high score is due to the potential for complete system compromise, including unauthorized access to sensitive data, data manipulation, and potential loss of data integrity.
• Impact: The vulnerability can lead to unauthorized access to the database, allowing attackers to read, modify, or delete data. This can result in significant data breaches, loss of confidentiality, and potential disruption of library services.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• SQL Injection: Attackers can inject malicious SQL code into the supplierid or serialid parameters, which are not properly sanitized. This can allow them to execute arbitrary SQL commands on the database.
• Data Exfiltration: By crafting specific SQL queries, attackers can extract sensitive information from the database, including user data, library records, and administrative information.
• Data Manipulation: Attackers can modify database entries, leading to incorrect records and potential disruption of library operations.
• Denial of Service (DoS): Attackers can execute SQL commands that overload the database, causing it to become unresponsive or crash.

Exploitation Methods:

• Manual Exploitation: Attackers can manually craft SQL injection payloads and send them via HTTP requests to the vulnerable endpoint.
• Automated Tools: Attackers can use automated SQL injection tools to identify and exploit the vulnerability, making it easier to extract large amounts of data quickly.

3. Affected Systems and Software Versions

Affected Software:

• Koha: Versions before 24.11.02 are affected by this vulnerability.

Affected Systems:

• Library Systems: Any library or institution using Koha ILS versions prior to 24.11.02 is at risk.
• Web Servers: Servers hosting the Koha application and handling requests to the /serials/lateissues-export.pl script are directly impacted.

4. Recommended Mitigation Strategies

Immediate Actions:

• Upgrade: Upgrade to Koha version 24.11.02 or later, which includes the fix for this vulnerability.
• Patch: Apply any available patches or hotfixes provided by the Koha community.

Long-Term Mitigations:

• Input Validation: Implement robust input validation and sanitization for all user inputs, especially those used in SQL queries.
• Parameterized Queries: Use parameterized queries or prepared statements to prevent SQL injection.
• Web Application Firewall (WAF): Deploy a WAF to monitor and block malicious SQL injection attempts.
• Regular Audits: Conduct regular security audits and code reviews to identify and mitigate similar vulnerabilities.

5. Impact on Cybersecurity Landscape

Broader Implications:

• Data Breaches: The vulnerability highlights the risk of data breaches in library systems, which often handle sensitive user information.
• Supply Chain Risks: Libraries and institutions relying on third-party software like Koha need to be vigilant about vulnerabilities in their supply chain.
• Compliance: Organizations must ensure compliance with data protection regulations, which may require immediate action to mitigate such vulnerabilities.

Industry Trends:

• Increased Awareness: This vulnerability underscores the need for increased awareness and training in secure coding practices.
• Proactive Security: The cybersecurity community is moving towards more proactive measures, including regular updates, patches, and continuous monitoring.

6. Technical Details for Security Professionals

Vulnerability Details:

• Location: The vulnerability is located in the GetLateOrMissingIssues function within the C4/Serials.pm module.
• Parameters: The supplierid and serialid parameters are not properly sanitized, allowing SQL injection.

Exploitation Example:

supplierid=1'; DROP TABLE users; --

This payload, if injected into the supplierid parameter, could potentially drop the users table from the database.

Mitigation Code Example:

# Example of using parameterized queries in Perl
my $sth = $dbh->prepare("SELECT * FROM issues WHERE supplierid = ? AND serialid = ?");
$sth->execute($supplierid, $serialid);
