Summary
rConfig before 8.2.13 has a path traversal vulnerability in the download_export() method, allowing authenticated attackers to read arbitrary files by supplying ../ sequences in the filename parameter. Sensitive files like environment files with encryption keys, database credentials, and mail config can be accessed.
Risk Assessment
Risk of sensitive data exposure, including credentials and keys, potentially leading to further attacks on the infrastructure.
Recommendation
Update rConfig to version 8.2.13 or later, which includes the fix.
Other vulnerabilities in rConfig
See all- CVE-2021-29006Medium
rConfig 3.9.6 is affected by a Local File Disclosure vulnerability. An authenticated user may successfully download any file on the server.
- CVE-2020-10221HighActively exploited
lib/ajaxHandlers/ajaxAddTemplate.php in rConfig through 3.94 allows remote attackers to execute arbitrary OS commands via shell metacharacters in the fileName POST parameter.
- CVE-2023-39110High
rconfig v3.9.4 was discovered to contain a Server-Side Request Forgery (SSRF) via the path parameter at /ajaxGetFileByPath.php. This vulnerability allows authenticated attackers to make arbitrary requests via injection of crafted URLs.
- CVE-2023-39109High
rconfig v3.9.4 was discovered to contain a Server-Side Request Forgery (SSRF) via the path_a parameter in the doDiff Function of /classes/compareClass.php. This vulnerability allows authenticated attackers to make arbitrary requests via injection of crafted URLs.
- CVE-2023-39108High
In version 3.9.4 of rconfig, a Server-Side Request Forgery (SSRF) vulnerability was discovered in the path_b parameter of the doDiff function in /classes/compareClass.php. This allows authenticated attackers to make arbitrary requests by injecting crafted URLs.
- CVE-2021-29005High
In rConfig 3.9.6, insecure permissions for the chmod command exist. After installation, the apache user can execute chmod as root without a password, allowing a low-privilege attacker to gain root access to the server.
- CVE-2021-29004High
SQL Injection vulnerability in rConfig 3.9.6 allows an authenticated attacker to inject malicious SQL code. If the MySQL server does not have --secure-file-priv set and is on the same host as rConfig, the attacker can upload a webshell and gain remote access.
Original NVD description (English source)
rConfig before 8.2.13 contains a path traversal vulnerability that allows authenticated attackers to read arbitrary files by supplying unsanitized directory traversal sequences in the filename GET parameter of the download_export() method. Attackers can craft requests with ../ sequences to escape the exports base directory and access sensitive files readable by the web server process, including application environment files containing encryption keys, database credentials, and mail configuration.
