-\\Vulnerable:
WBB3 rGallery 1.2.3
-\\Discussion
WBB3 rGallery is prone to an SQL-injection vulnerability because it fails to sufficiently sanitize
user-supplied data before using it in an SQL query.
Exploiting this issue could allow an attacker to compromise the application, access or modify data,
or exploit latent vulnerabilities in the underlying database.
WBB3 rGallery 1.2.3 is vulnerable; other version may also be affected.
-\\Exploit(s)/PoC(s):
Attackers can use a browser to exploit this issue.
The following exploit is available:
