Product: Guard
Internal reference: 40003 (Bug ID)
Vulnerability type: SQL Injection (CWE-89)
Vulnerable version: 2.0.0-rev7 and earlier
Vulnerable component: guard
Report confidence: Confirmed
Solution status: Fixed by Vendor
Fixed version: 2.0.0-rev8
Vendor notification: 2015-07-28
Solution date: 2015-08-03
CVE reference: CVE-2015-5703
CVSSv2: 7.9 
(AV:N/AC:H/Au:M/C:P/I:C/A:N/E:F/RL:U/RC:C/CDP:MH/TD:ND/CR:H/IR:H/AR:M)

Vulnerability Details:
A SQL injection vulnerability at the public key discovery API call has been 
identified that allows to execute arbitrary SQL statements in the context of 
the OX Guard database user. Valid user credentials are required to access this 
API and execute malicious statements.

Risk:
The vulnerability can be exploited to access confidential information like 
system configuration, mail addresses or other database content. Credentials are 
stored as salted hashes and PGP keys are stored encrypted. This makes it very 
expensive to extract plain-text data from it. There is no indicator that this 
vulnerability was been publicly known or exploited.

Solution:
Providers should update to Patch Release 2.0.0-rev8, or any later version.
