Description:
The vendor has reported several vulnerabilities in Cisco ONS 15000 based products, allowing malicious people to cause a Denial of Service or bypass authentication.
1) The XTC, TCC/TCC+/TCC2 and TCCi/TCC2 control cards fail to handle multiple malformed IP packets. This may allow malicious people to cause the control cards to reset.
2) The XTC, TCC/TCC+/TCC2 and TCCi/TCC2 control cards fail to handle multiple malformed ICMP packets. This may allow malicious people to cause the control cards to reset.
3) The XTC, TCC/TCC+/TCC2, TCCi/TCC2 and TSC control cards fail to handle multiple malformed TCP packets. This may allow malicious people to cause the control cards to reset.
4) The XTC, TCC/TCC+/TCC2 and TCCi/TCC2 control cards fail to handle TCP sequences which don't send the final ACK but send an invalid reply instead. This may allow malicious people to cause the control cards to reset.
5) The XTC, TCC/TCC+/TCC2, TCCi/TCC2 and TSC control cards fail to handle multiple malformed UDP packets. This may allow malicious people to cause the control cards to reset.
6) The XTC, TCC/TCC+/TCC2 and TCCi/TCC2 control cards fail to handle multiple malformed SNMP packets. This may allow malicious people to cause the control cards to reset.
7) The TL1 login interface allows malicious people to authenticate by supplying any string longer than 10 characters as a password for any account with an empty password.
According to the vendor the above issues only affect the control cards, however it also causes timing problems for synchronous data channels. Asynchronous data channels are not affected.
