"1. Fixed SQL injection issue in project object class
2. Fixed XSS issues with select users and select projects widgets
3. Upgrade script steps can't be triggered without logging in as
Additionally Stratsec Research has provided the following more
detailed description of the vulnerabilities identified by
Andrew Horton, Steven Seeley and Pedram Hayati:
"Remote Code Execution and Remote Command Execution
Remote code execution and remote command execution vulnerabilities
allow an attacker to fully compromise the underlying application and
potentially the underlying OS.
SQL injection allows for an attacker to manipulate the backend database
and steal sensitive information from the database. An SQL injection
attack often leads to the complete compromise of the underlying OS.
Authentication bypass often allows an attacker to perform trusted
actions within the application without supplying valid credentials.
This may lead to unauthorised manipulation of the application and its
Cross-site scripting vulnerabilities in an application potentially
allow an attacker to execute malicious script on other users systems
and hence compromise their sessions, authentication credentials, or
even conduct other malicious activity.
XQuery (XPath) is a language for addressing parts of XML document.
Similar to SQL, XQuery is used to query XML documents. The input data
to XQuery must be sanitised in order to avoid malformed queries and
possibly access to the entire XML document.
Username enumeration allows for an external attacker to enumerate
valid usernames for the application. This type of vulnerability is
generally within login functionality." 
The vendor recommends upgrading to the latest version of activeCollab
to correct these issues.
