[原文]SQL injection vulnerability in (1) fdelmail.asp, (2) addressc.asp, and possibly (3) postmail.asp and (4) fmvmail.asp in CMailServer 5.2 allow remote attackers to inject arbitrary SQL commands and delete mail metadata or e-mail addresses of contacts via the indexOfMail parameter.
CMailServer contains a flaw that will allow an attacker to inject arbitrary SQL code. The problem is that the indexOfMail variable in the fdelmail.asp module is not verified properly and will allow an attacker to inject or manipulate SQL queries.
Upgrade to version 5.2.1 or higher, as it has been reported to fix this vulnerability. An upgrade is required as there are no known workarounds.
