CVE-2012-1033

The resolver in ISC BIND 9 through 9.8.1-P1 overwrites cached server names and TTL values in NS records during the processing of a response to an A record query, which allows remote attackers to trigger continued resolvability of revoked domain names via a "ghost domain names" attack...

CVE-2011-3274: Undefined Security Weakness

Unspecified vulnerability in Cisco IOS 12.2SRE before 12.233SRE4, 15.0, and 15.1, and IOS XE 2.1.x through 3.3.x, when an MPLS domain is configured, allows remote attackers to cause a denial of service device crash via a crafted IPv6 packet, related to an expired MPLS TTL, aka Bug ID CSCto07919...

broadcast-ping NSE Script

Sends broadcast pings on a selected interface using raw ethernet packets and outputs the responding hosts' IP and MAC addresses or if requested adds them as targets. Root privileges on UNIX are required to run this script since it uses raw sockets. Most operating systems don't respond to...

Nmap NSE net: firewalk

Tries to discover firewall rules using an IP TTL expiration technique known as firewalking. The scan requires a firewall or 'gateway' and a metric or 'target'. For each filtered port on the target, send a probe with an IP TTL one greater than the number of hops to the gateway. The TTL can be give...

firewalk NSE Script

Tries to discover firewall rules using an IP TTL expiration technique known as firewalking. To determine a rule on a given gateway, the scanner sends a probe to a metric located behind the gateway, with a TTL one higher than the gateway. If the probe is forwarded by the gateway, then we can expec...

Checkpoint VPN-1 PAT信息泄露漏洞

CVECAN ID: CVE-2008-5849 CheckPoint防火墙/VPN解决方案可为组织提供网络架构和信息安全保护。 对于启用了端口地址翻译（PAT）的CheckPoint VPN-1防火墙，如果远程攻击者向防火墙的18264/tcp端口发送设置有很低TTL值的报文的话，就可以触发ICMPTIMXCEEDINTRANS响应，而响应的封装IP报文中包含有内部IP地址，如下所示： 14:56:25.169480 IP tos 0xe0, ttl 255, id 21407, offset 0, flags none, proto: ICMP 1, length: 68...

Snort碎片重组TTL值导致漏报漏洞

BUGTRAQ ID: 29327 CVECAN ID: CVE-2008-1804 Snort是广泛部署的开放源码网络入侵检测系统（IDS）。 Snort没有正确地重组IP报文，远程攻击者可能利用此漏洞绕过检测。 在接收入站碎片时，Snort检查碎片的存活时间（TTL）值并与初始碎片的TTL做比较。如果二者之间的差异大于所配置的量（默认最大值为5）的话，就会丢弃碎片，也无法对其应用规则，这导致Snort无法过滤或检查有效的通讯。 Snort Project Snort 2.8 Snort Project Snort 2.6 临时解决方法：...
