Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Buffer Overflow via Environment Variables This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
- Server Side Include (SSI) Injection An attacker can use Server Side Include (SSI) Injection to send code to a web application that then gets executed by the web server. Doing so enables the attacker to achieve similar results to Cross Site Scripting, viz., arbitrary code execution and information disclosure, albeit on a more limited scale, since the SSI directives are nowhere near as powerful as a full-fledged scripting language. Nonetheless, the attacker can conveniently gain access to sensitive files, such as password files, and execute shell commands.
- Cross Zone Scripting An attacker is able to cause a victim to load content into their web-browser that bypasses security zone controls and gain access to increased privileges to execute scripting code or other web objects such as unsigned ActiveX controls or applets. This is a privilege elevation attack targeted at zone-based web-browser security. In a zone-based model, pages belong to one of a set of zones corresponding to the level of privilege assigned to that page. Pages in an untrusted zone would have a lesser level of access to the system and/or be restricted in the types of executable content it was allowed to invoke. In a cross-zone scripting attack, a page that should be assigned to a less privileged zone is granted the privileges of a more trusted zone. This can be accomplished by exploiting bugs in the browser, exploiting incorrect configuration in the zone controls, through a cross-site scripting attack that causes the attackers' content to be treated as coming from a more trusted page, or by leveraging some piece of system functionality that is accessible from both the trusted and less trusted zone. This attack differs from "Restful Privilege Escalation" in that the latter correlates to the inadequate securing of RESTful access methods (such as HTTP DELETE) on the server, while cross-zone scripting attacks the concept of security zones as implemented by a browser.
- Cross Site Scripting through Log Files An attacker may leverage a system weakness where logs are susceptible to log injection to insert scripts into the system's logs. If these logs are later viewed by an administrator through a thin administrative interface and the log data is not properly HTML encoded before being written to the page, the attackers' scripts stored in the log will be executed in the administrative interface with potentially serious consequences. This attack pattern is really a combination of two other attack patterns: log injection and stored cross site scripting.
- Command Line Execution through SQL Injection An attacker uses standard SQL injection methods to inject data into the command line for execution. This could be done directly through misuse of directives such as MSSQL_xp_cmdshell or indirectly through injection of data into the database that would be interpreted as shell commands. Sometime later, an unscrupulous backend application (or could be part of the functionality of the same application) fetches the injected data stored in the database and uses this data as command line arguments without performing proper validation. The malicious data escapes that data plane by spawning new commands to be executed on the host.

| description | BUGTRAQ ID: 31359 CVE ID: CVE-2008-3810 CVE-2008-3811 CNCVE ID：CNCVE-20083810 CNCVE-20083811 Cisco IOS Skinny Call控制协议是Cisco专利的语音通讯协定，被用来促进在 CallManager与IP电话之间的来电管理功能。 Cisco IOS SCCP协议存在多个问题，远程攻击者可以利用漏洞对服务进行拒绝服务攻击。 Skinny Call Control Protocol (SCCP)在SCCP客户端和呼叫管理器(Call Manager)之间启用语音通信，通常CM默认在TCP 2000端口对SCCP客户端进行服务，初始化时SCCP客户端通过建立TCP连接连接CM，如果存在第二CM的情况下，客户端也会建立TCP连接。 由于NAT Skinny应用层网关(ALG)能重组skinny控制消息，NAP SCCP分片支持功能能防止在TCP段上失败的skinny控制消息交换。一个需要IP或端口转化的分段负载将不会被丢弃。NAT SCCP分片支持功能在Cisco IOS 12.4(6)T上实现。 一系列分片SCCP消息可导致运行了NAT SCCP分片支持功能的Cisco IOS路由器重载。 相关漏洞的Cisco Bug ID为CSCsg22426和CSCsi17020。CVE ID为 CVE-2008-3810和CVE-2008-3811。 Cisco IOS 12.4XW Cisco IOS 12.4XV Cisco IOS 12.4XT Cisco IOS 12.4XP Cisco IOS 12.4XN Cisco IOS 12.4XM Cisco IOS 12.4XL Cisco IOS 12.4XK Cisco IOS 12.4XJ Cisco IOS 12.4XG Cisco IOS 12.4XF Cisco IOS 12.4XE Cisco IOS 12.4XC Cisco IOS 12.4T Cisco IOS 12.4SW Cisco IOS 12.4MR Cisco IOS 12.4MD 可参考如下安全公告获得补丁信息： <a href=http://www.cisco.com/warp/public/707/cisco-sa-20080924-sccp.shtml target=_blank>http://www.cisco.com/warp/public/707/cisco-sa-20080924-sccp.shtml</a> |
