CAPEC-107: Cross Site Tracing
CAPEC版本: 3.9
更新日期: 2023-01-24
攻击模式描述
Cross Site Tracing (XST) enables an adversary to steal the victim's session cookie and possibly other authentication credentials transmitted in the header of the HTTP request when the victim's browser communicates to a destination system's web server.
执行流程
步骤 1 Explore
[Determine if HTTP Trace is enabled] Determine if HTTP Trace is enabled at the web server with which the victim has an active session
- An adversary may issue an HTTP Trace request to the target web server and observe if the response arrives with the original request in the body of the response.
步骤 2 Experiment
[Identify mechanism to launch HTTP Trace request] The adversary attempts to force the victim to issue an HTTP Trace request to the targeted application.
- The adversary probes for cross-site scripting vulnerabilities to force the victim into issuing an HTTP Trace request.
步骤 3 Exploit
[Create a malicious script that pings the web server with HTTP TRACE request] The adversary creates a malicious script that will induce the victim's browser to issue an HTTP TRACE request to the destination system's web server. The script will further intercept the response from the web server, pick up sensitive information out of it, and forward to the site controlled by the adversary.
- The adversary's malicious script circumvents the httpOnly cookie attribute that prevents from hijacking the victim's session cookie directly using document.cookie and instead leverages the HTTP TRACE to catch this information from the header of the HTTP request once it is echoed back from the web server in the body of the HTTP TRACE response.
步骤 4 Exploit
[Execute malicious HTTP Trace launching script] The adversary leverages an XSS vulnerability to force the victim to execute the malicious HTTP Trace launching script
步骤 5 Exploit
[Intercept HTTP TRACE response] The adversary's script intercepts the HTTP TRACE response from teh web server, glance sensitive information from it, and forward that information to a server controlled by the adversary.
前提条件
- HTTP TRACE is enabled on the web server
- The destination system is susceptible to XSS or an adversary can leverage some other weakness to bypass the same origin policy
- Scripting is enabled in the client's browser
- HTTP is used as the communication protocol between the server and the client
所需技能

后果影响
影响范围: Confidentiality
技术影响: Read Data
影响范围: Confidentiality Access Control Authorization
技术影响: Gain Privileges
影响范围: Integrity
技术影响: Modify Data
缓解措施
Administrators should disable support for HTTP TRACE at the destination's web server. Vendors should disable TRACE by default.
Patch web browser against known security origin policy bypass exploits.
