SHELLCODE: x86 Intel Architecture Instruction Set NOOP Slide (HTTP-Request)
This signature detects attempts to exploit a known vulnerability against Web servers on Intel x86 platforms. Attackers can use the "No-Op Slide" attack to pad the stack with "No Operation" x86 CPU instructions and overwrite the return address. A successful attack might allow arbitrary code execution.
Extended Description
Versions 2.6, 7, and 8 of Sun Microsystem's Solaris operating environment ship with service called 'snmpXdmid'. This daemon is used to map SNMP management requests to DMI requests and vice versa. SnmpXdmid contains a remotely exploitable buffer overflow vulnerability. The overflow occurs when snmpXdmid attempts to translate a 'malicious' DMI request into an SNMP trap. SnmpXdmid runs with root privileges and any attacker to successfully exploit this vulnerability will gain superuser access immediately.
