Detailsinfo

A vulnerability, which was classified as critical, was found in Koha Community Koha up to 24.11.17/25.05.12/25.11.6/26.05.1. This affects the function Koha::AdditionalContents->search_for_display of the component Patron Lang Field. The manipulation of the argument lang with an unknown input leads to a sql injection vulnerability. CWE is classifying the issue as CWE-89. The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

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 borrowers => edit_borrowers permission to cause a time-based denial of service by storing a SQL payload in a patron lang field. The value is concatenated raw into a subquery in Koha::AdditionalContents->search_for_display when an issue slip is printed for the affected patron. The 25-character column length limits exploitation to timing attacks; data extraction is not practical. The stored payload executes on each subsequent issue-slip print, scaling linearly with the SLEEP value and the number of slip-news rows.
