Detailsinfo

A vulnerability was found in Nur-Alam39 bus-ticket (the affected version is unknown). It has been declared as critical. This vulnerability affects the function mysqli_query of the file bus_info.php. The manipulation of the argument busid with an unknown input leads to a sql injection vulnerability. The CWE definition for the vulnerability is 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. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

Nur-Alam39 bus-ticket (no released versions; latest commit 459cabdbeb99c00225b26e46e3c2c30ae1de7bad) contains an unauthenticated SQL injection vulnerability in bus_info.php. The busid parameter received via HTTP POST is concatenated directly into a MySQL query (select * from bus_info where id=$busid) without sanitization, escaping, or parameterization, and in a numeric (unquoted) context. A remote, unauthenticated attacker can inject arbitrary SQL — for example a UNION-based payload such as busid=-1 UNION SELECT 1,2,3,4,5,6 — to read arbitrary data from the bus_service database. The application connects to the database as the MySQL root account with an empty password, increasing the potential impact. The query is executed via mysqli_query(), which does not permit stacked (semicolon-separated) statements.

The weakness was released by Eshmurzayev Abbos. The advisory is available at github.com. This vulnerability was named CVE-2026-55740 since 06/17/2026. The exploitation appears to be easy. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. Technical details are known, but there is no available exploit.
