# CVE-2018-5767-AC9
An implementation of a proof-of-concept for CVE-2018-5767 (https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2018-5767)
The following is an actualization of CVE-2018-5767, a vulnerability which
exploits an unguarded call to sscanf that occurs when parsing the 'Cookie'
header for a password. The vulnerability was initially discovered in, and
reported for, the AC15 model router, but has been rediscovered in several
different routers in this product line. This implementation sees it exploit the
model AC9, which is not presently covered by any CVE. A memory address for the
base of libc known to work on this router is 0x2ad6d000.
