[原文]SQL injection vulnerability in index.php in Netref 3.0 allows remote attackers to execute arbitrary SQL commands via the cat parameter. NOTE: the provenance of this issue is unknown; the details were obtained solely from third party sources.
Netref contains a flaw that may allow an attacker to carry out an SQL injection attack. The issue is due to the index.php script not properly sanitizing user-supplied input to the 'cat' variable. This may allow an attacker to inject or manipulate SQL queries in the back-end database.
Currently, there are no known upgrades, patches, or workarounds available to correct this issue.
