Multiple SQL injection vulnerabilities in Plogger 3.0 and earlier allow remote attackers to execute arbitrary SQL commands via (1) the checked array parameter to plog-download.php in an album action and (2) unspecified parameters to plog-remote.php, and (3) allow remote authenticated administrators to execute arbitrary SQL commands via the activate parameter to admin/plog-themes.php, related to theme_dir settings.
The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
