Fortinet Discovers QIWI POS INGENICO DLL Preloading Vulnerability
Fortinet's FortiGuard Labs has discovered a DLL preloading vulnerability in Qiwi POS InGenico.
Qiwi POS InGenico can be used to allow organizing payment services in places without the need to install a self-service terminal.
Qiwi POS InGenico for Windows is susceptible to a DLL preloading vulnerability. The issue occurs when the application looks to load a DLL for execution and an attacker provides a malicious DLL to use instead. The application generally follows a specific search path to locate the DLL. The vulnerability can be exploited by a simple file write (or potentially an over-write) which results in a foreign DLL running under the context of the application.
No vendor patch is available.
Fortinet reported the vulnerability to Qiwi on July 18, 2017.
Qiwi confirmed the vulnerability on July 19, 2017.
