CVE-2020-10512Network attack vector

Authenticated arbitrary SQL execution via calendar parameter

Published Apr 15, 2020 · Updated Sep 16, 2024

SQL injection in HGiga C&Cmail CCMAILQ and CCMAILN allows remote authenticated users to execute arbitrary SQL through a URL parameter. The modify_cmc.php calendar endpoint processes a crafted URL parameter as SQL syntax instead of treating it solely as data. Low-privilege web access is required; successful injection can read account credentials, change passwords, or write a web shell.
