CWE-368 上下文切换时的竞争条件
Context Switching Race Condition
结构: Simple
Abstraction: Base
状态: Draft
被利用可能性: unkown
基本描述
A product performs a series of non-atomic actions to switch between contexts that cross privilege or other security boundaries, but a race condition allows an attacker to modify or misrepresent the product's behavior during the switch.
扩展描述
This is commonly seen in web browser vulnerabilities in which the attacker can perform certain actions while the browser is transitioning from a trusted to an untrusted domain, or vice versa, and the browser performs the actions on one domain using the trust level and resources of the other domain.

| CVE-2009-1837 | Chain: race condition (CWE-362) from improper handling of a page transition in web client while an applet is loading (CWE-368) leads to use after free (CWE-416) | https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-1837 |
| CVE-2004-2260 | Browser updates address bar as soon as user clicks on a link instead of when the page has loaded, allowing spoofing by redirecting to another page using onUnload method. this is one example of the role of "hooks" and context switches, and should be captured somehow - also a race condition of sorts | https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2004-2260 |
| CVE-2004-0191 | XSS when web browser executes Javascript events in the context of a new page while it's being loaded, allowing interaction with previous page in different domain. | https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2004-0191 |
| CVE-2004-2491 | Web browser fills in address bar of clicked-on link before page has been loaded, and doesn't update afterward. | https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2004-2491 |
Notes
Relationship
Can overlap signal handler race conditions.
Research Gap
Under-studied as a concept. Frequency unknown; few vulnerability reports give enough detail to know when a context switching race condition is a factor.
