Firm Allegedly Hiding Cisco Bugs

Filed under: — By Aviran Mordo @ 8:33 am

The computer security researcher who revealed a serious vulnerability in the operating system for Cisco Systems routers this year says he discovered 15 additional flaws in the software that have gone unreported until now, one of which is more serious than the bug he made public last summer.

Mike Lynn, a former security researcher with Internet Security Systems, or ISS, said three of the flaws can give an attacker remote control of Cisco’s routing and gateway hardware, essentially allowing an intruder to run malicious code on the hardware. The most serious of the three would affect nearly every configuration of a Cisco router, he said.

Lynn, who now works for Cisco competitor Juniper Networks, told Wired News that ISS has known about additional flaws in the Cisco software for months but hasn’t told Cisco about them. This is serious, Lynn said, because attackers may already be developing exploits for the vulnerabilities. Cisco’s source code was reportedly stolen in 2004 and, while doing research on the IOS software, Lynn found information on a Chinese-language website that indicated to him that Chinese attackers were aware of the security flaws in IOS and could be exploiting them.
