BigAnt IM Message server and components contain multiple vulnerabilities which could allow an attacker to perform administrative functions on the the system
CWE-89: Improper Neutralization of Special Elements used in an SQL Command (‘SQL Injection’) - CVE-2012-6273
During the SHU request (search user) from the bigant messaging client, a sql query is built from a template and sent via a http like header. Proper sanitization is not performed. It has been reported this can be demonstrated by opening up the BigAnt Messenger Client, logging into a server, and searching for an 'Account/Full Name' of blah' OR hs_User.Col_Pword LIKE '[a-z]
CWE-280: Improper Handling of Insufficient Permissions or Privileges - CVE-2012-6274
Arbitrary unauthenticated file upload in BigAnt IM Server. It has been reported that authentication for file uploads is not enforced. Uploaded files were reported to be saved to C:\Program Files\BigAntSoft\AntServer\DocData\Public.
CWE-121: Stack-based Buffer Overflow - CVE-2012-6275
Buffer overflow in AntDS.exe component of BigAnt Message server when handling the filename
header in SCH requests and userid
component of DUPF requests.
A remote unauthenticated attacker may obtain sensitive information, cause a denial of service condition or execute arbitrary code with the privileges of the application.
We are currently unaware of a practical solution to this problem.
Restrict access
As a general good security practice, only allow connections from trusted hosts and networks. Note that restricting access does not prevent SQLi, unauthenticated file uploads, or denial of service attacks since the attack comes as an HTTP request from a legitimate user’s host. Restricting access would prevent an attacker from accessing a web interface using stolen credentials from a blocked network location.
