Description
This security bulletin contains information about 5 secuirty vulnerabilities.
1) Arbitrary file upload (CVE-ID: CVE-2021-31542)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to insufficient validation of file during file upload via the MultiPartParser, UploadedFile, and FieldFile methods. A remote attacker can upload a file with a specially crafted filename containing directory traversal characters and overwrite arbitrary files on the system.
Successful exploitation of the vulnerability may allow an attacker to compromise the affected system.
2) Path traversal (CVE-ID: CVE-2021-28658)
The vulnerability allows a remote attacker to perform directory traversal attacks.
The vulnerability exists due to input validation error when processing directory traversal sequences in MultiPartParser. A remote attacker can use a specially crafted files with suitably crafted file names and read arbitrary files on the system.
3) Path traversal (CVE-ID: CVE-2021-33203)
The vulnerability allows a remote attacker to perform directory traversal attacks.
The vulnerability exists due to input validation error when processing directory traversal sequences within the "admindocs" view. A remote authenticated attacker can send a specially crafted HTTP request and read arbitrary files on the system.
4) Server-Side Request Forgery (SSRF) (CVE-ID: CVE-2021-33571)
The disclosed vulnerability allows a remote attacker to perform SSRF attacks.
The vulnerability exists due to insufficient validation of user-supplied input in the "URLValidator", "validate_ipv4_address()" and "validate_ipv46_address()" . A remote attacker can send a specially crafted HTTP request and trick the application to initiate requests to arbitrary systems.
Successful exploitation of this vulnerability may allow a remote attacker gain access to sensitive data, located in the local network or send malicious requests to other servers from the vulnerable system.
5) Path traversal (CVE-ID: CVE-2021-3281)
The vulnerability allows a remote attacker to perform directory traversal attacks.
The vulnerability exists due to input validation error when processing directory traversal sequences inside archives with "django.utils.archive.extract()" function. A remote attacker can pass specially crafted archive to the application and write files to arbitrary directory on the system.
