Cisco Secure Content Accelerator Vulnerable to SSL Worm
6 Oct. 2002
Summary
As we reported in our previous article: "Slapper" OpenSSL/Apache Worm Propagation, a worm has been infecting and spreading from these infected machines to other machines, by means of exploiting a well known vulnerability in OpenSSL, it has been now made clear that Cisco's Secure Content Accelerator (un-patched version) is also vulnerable to attack, and is being actively compromised.
Vulnerable systems:
* Cisco SCA 11000 Series Secure Content Accelerator
Attempts to exploit the vulnerability described in CAN-2002-0656 cause the SCA 11000 (all tested software releases) to spontaneously reboot, resulting in at least a denial of service. This product incorporates code from an older OpenSSL release, and thus shares the same vulnerability. There is no known means to work around this issue, short of disabling SSL services on the system.
No official fix is as yet available from Cisco for this issue, and no advisory has been released. Impact is likely equivalent to impact on the SonicWALL product.
