Vulnerability Description

A stored SQL injection vulnerability in Koha through 24.11.17, 25.05.12, 25.11.06, and 26.05.01 allows authenticated staff with the tools => label_creator permission to execute arbitrary SQL via the image_name field of a patron card layout. The image_name value is stored verbatim in the layout XML and later concatenated raw into a SQL query in patroncards/create-pdf.pl when a patron card batch is printed. An attacker can read the entire Koha database including patron PII and staff bcrypt password hashes via error-based or time-based blind injection.

Recommended Actions

1. Maintain the observed Atomicorp protections. Keep your Atomicorp commercial rules current and confirm that the selected observed rules (340016 , 340017 , 340144 , 340145 , 340156 , 340157 , 341145 , 341245 , 360147 , 360148 , 380026 , 380122 , 390572 ) have not been locally disabled. Atomicorp commercial rules are enabled by default. If you use Atomic WAF, review the applicable policy and rule settings.

2. Apply the vendor’s remediation. WAF protection is defense in depth and does not replace upgrading or following the affected vendor’s guidance.

   • Affected versions: Koha Community Koha versions earlier than 24.11.18.
   • Affected versions: Koha Community Koha versions earlier than 25.05.13.
   • Affected versions: Koha Community Koha versions earlier than 25.11.07.
   • Affected versions: Koha Community Koha versions earlier than 26.05.02.
   • No specific CNA/vendor solution or workaround is included in the current CVE Record (opens in a new tab) . Review the vendor’s security advisories and supported-release guidance before making changes.

3. Validate after changes. Confirm rule updates are current, review WAF events for the affected application, and test application behavior after vendor upgrades, mitigations, or local policy changes.

Research Notes

Atomicorp WAF protections are designed around attack techniques and exploit behaviors, allowing existing protections to apply across multiple vulnerabilities without requiring a unique rule for every CVE.

Research Note Context

This research note documents exploit-technique analysis associated with this vulnerability and references Atomicorp WAF protections observed during engineering review, testing, or validation activities.

Atomicorp security controls are generally designed to identify and mitigate attack techniques and exploit behaviors rather than individual CVE identifiers. As a result, protections developed for one vulnerability may also apply to related attack variants and future vulnerabilities using similar techniques.
