[原文]** DISPUTED ** SQL injection vulnerability in index.php in ATutor 1.5.3 allows remote attackers to execute arbitrary SQL commands via the fid parameter. NOTE: this issue has been disputed by the vendor, who states "The mentioned SQL injection vulnerability is not possible." However, the relevant source code suggests that this issue may be legitimate, and the parameter is cleansed in 18.104.22.168.
ATutor 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 'fid' variable. This may allow an attacker to inject or manipulate SQL queries in the back-end database.
Note: the vendor disputes the validity of this flaw
Currently, there are no known upgrades, patches, or workarounds available to correct this issue.
