Vulnerability Details:
The SQL injection vulnerability was found in an HTTP post request of the
AJAX component from the sysPass software.
The attribute getAccounts is not correctly sanitized and therefore can be
abused to inject arbitrary SQL statements.
This SQL injection vulnerability can be exploited by an authenticated
attacker by sending a specially crafted HTTP POST request (see PoC
section).
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Proof of Concept (PoC):
The following HTTP request can be used to extract information from the
database:
