TITLE:
EMC Retrospect Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA31186

VERIFY ADVISORY:
http://secunia.com/advisories/31186/

CRITICAL:
Less critical

IMPACT:
Brute force, Exposure of sensitive information, DoS

WHERE:
>From local network

SOFTWARE:
EMC Retrospect 7.x
http://secunia.com/product/7429/
EMC Retrospect Client for Windows 7.x
http://secunia.com/product/8531/

DESCRIPTION:
Some vulnerabilities and a security issue has been reported in EMC
Retrospect, which can be exploited by malicious people to disclose
sensitive information or cause a DoS (Denial of Service).

1) An error in retroclient.exe can be exploited to cause the process
to terminate via specially crafted packets sent to default port
497/TCP.

2) A NULL pointer dereference error can be exploited to cause a DoS
via specially crafted packets sent to default port 497/TCP.

3) It is possible to disclose e.g. the password hash in plaintext via
a specially crafted packet sent to the EMC Retrospect Client.
Additionally, the authentication module of the EMC Retrospect Server
reportedly uses a weak password hash arithmetic, which can be
brute-forced.

The vulnerabilities and security issue are reported in version
7.5.116 (Client) and 7.5.508 (Server).

SOLUTION:
Update to the latest versions.
