CVE-2022-25512	Server for Team Awareness Kit (TAK) application includes sensitive tokens in the JavaScript source code.
CVE-2022-24867	The LDAP password might be visible in the html code of a rendered page in an IT Asset Management tool.
CVE-2007-6197	Version numbers and internal hostnames leaked in HTML comments.

潜在缓解措施

Phases : Architecture and Design // System Configuration
Recommendations include removing the script from the web server and moving it to a location not accessible from the Internet.

检测方法

Automated Static Analysis

Automated static analysis, commonly referred to as Static Application Security Testing (SAST), can find some instances of this weakness by analyzing source code (or binary/compiled code) without having to execute it. Typically, this is done by building a model of data flow and control flow, then searching for potentially-vulnerable patterns that connect "sources" (origins of input) with "sinks" (destinations where the data interacts with external components, a lower layer such as the OS, etc.)

漏洞映射说明

依据 : This CWE entry is at the Base level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities.
备注 : Carefully read both the name and description to ensure that this mapping is an appropriate fit. Do not try to 'force' a mapping to a lower-level Base/Variant simply to comply with this preferred level of abstraction.
