CVE Descriptions

Unspecified vulnerability in Cisco IOS 12.0 through 12.4 allows context-dependent attackers to cause a denial of service (device restart and BGP routing table rebuild) via certain regular expressions in a "show ip bgp regexp" command. NOTE: unauthenticated remote attacks are possible in environments with anonymous telnet and Looking Glass access.

EPSS

EPSS is a scoring model that predicts the likelihood of a vulnerability being exploited.

EPSS Score

The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.

EPSS Percentile

The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other CVE.

source: https://www.securityfocus.com/bid/25352/info Cisco IOS is prone to a remote denial-of-service vulnerability because the software fails to properly handle certain CLI commands. To issue commands that trigger this vulnerability, attackers must be able to successfully authenticate to vulnerable devices. This may be achieved through remote anonymous means or by sending specially crafted input to web interfaces such as 'Looking Glass' web applications. Successfully exploiting this issue allows attackers to trigger device reboots, denying service to legitimate users. This issue is documented as Cisco bug ID CSCsb08386. Cisco IOS releases in the 12.0, 12.1, 12.2, 12.3, and 12.4 ranges are vulnerable to this issue. show ip bgp regexp (.*)(_\1)+ show ip bgp regexp ([0-9]*)(_\1)+
