This vulnerability allows remote attackers to execute arbitrary code on affected installations of Koha. Authentication is required to exploit this vulnerability. The specific flaw exists within the web service, which listens on TCP port 8081 by default. The issue results from the lack of proper validation of a user-supplied string before passing it to the eval function. An attacker can leverage this vulnerability to execute code in the context of the service account.

Koha's reports/borissuestop.pl builds dynamic SQL in sub calculate by concatenating several user-controlled request parameters directly into the query string. An authenticated staff user holding the reports module permission can inject arbitrary SQL and read any table reachable by the Koha database user, including borrowers (password hashes, two-factor secrets, personal data), apikeys, and sessions.

Koha's reports/issuesavgstats.pl builds dynamic SQL in sub calculate by concatenating several user-controlled request parameters directly into the query string. The Line and Column parameters are not validated against any whitelist and land verbatim in identifier positions (SELECT DISTINCTROW, GROUP BY, ORDER BY), and each Filter slot is concatenated raw into single-quoted LIKE, BETWEEN, and comparison fragments with no bound parameters.

Koha's reports/cataloguestats.pl builds dynamic SQL in sub calculate by interpolating the user-controlled Line and Column request parameters directly into identifier positions of the query (SELECT DISTINCTROW, GROUP BY, ORDER BY) with no whitelist validation.

Koha's reports/acquisitionsstats.pl builds its per-cell statistics query in sub calculate by interpolating the user-controlled Filter request parameters directly into WHERE fragments covering aqbasket.closedate, aqorders.datereceived, aqbooksellers.name, items.homebranch, items.ccode, biblioitems.itemtype, aqbudgets.budgetcode, aqorders.sort1, and aqorders.sort2.
