名称: Exposure of Backup File to an Unauthorized Control Sphere

A backup file is stored in a directory or archive that is made accessible to unauthorized actors.

基本信息

背景详情

引入方式

Operation : OMISSION: This weakness is caused by missing a security tactic during the architecture and design phase.
Array : This renaming may have been performed automatically by the web server, or manually by the administrator.

类： Not Language-Specific (Undetermined)

技术

类： Not Technology-Specific (Undetermined)
名称： Web Server (Undetermined)

常见后果

影响范围	影响	可能性
Confidentiality	Read Application Data 注意： At a minimum, an attacker who retrieves this file would have all the information contained in it, whether that be database calls, the format of parameters accepted by the application, or simply information regarding the architectural structure of your site. The source code for old files that were renamed in this manner and left in the webroot can often be retrieved.

观察示例

参考资料	描述
CVE-2024-7315	Chain: WordPress plugin does not use sufficient randomness when generating the filename for a backup (CWE-340), allowing attackers to obtain backup files (CWE-530)

潜在缓解措施

Phases : Policy
Recommendations include implementing a security policy within your organization that prohibits backing up web application source code in the webroot.

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.)
有效性 : High

漏洞映射说明

依据 : This CWE entry is at the Variant 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.
