Description
This security bulletin contains information about 9 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-2021-33203)
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.
3) 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.
4) Improper access control (CVE-ID: CVE-2021-44420)
The vulnerability allows a remote attacker to gain unauthorized access to otherwise restricted functionality.
The vulnerability exists due to improper access restrictions. A remote attacker can send specially crafted HTTP requests for URLs with trailing newlines and bypass an upstream access control based on URL paths.
5) Resource management error (CVE-ID: CVE-2021-45115)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper management of internal resources in UserAttributeSimilarityValidator when evaluating submitted password that were artificially large in relative to the comparison values. A remote attacker can pass specially crafted password to the application and perform a denial of service (DoS) attack.
6) Information exposure through externally-generated error message (CVE-ID: CVE-2021-45116)
The vulnerability allows a remote user to gain access to potentially sensitive information.
The vulnerability exists due to excessive data output by the application while handling error conditions in the dictsort template filter. A remote user can obtain sensitive information on the system.
7) Path traversal (CVE-ID: CVE-2021-45452)
The vulnerability allows a remote user to perform directory traversal attacks.
The vulnerability exists due to input validation error when processing directory traversal sequences in the Storage.save() method. A remote user can pass a specially crafted HTTP filename to the application and write the file outside of the intended directory.
8) Infinite loop (CVE-ID: CVE-2022-23833)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to infinite loop when parsing files. A remote attacker can upload a specially crafted file to the server, consume all available system resources and cause denial of service conditions.
9) Cross-site scripting (CVE-ID: CVE-2022-22818)
The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.
The vulnerability exists due to insufficient sanitization of user-supplied data when displaying information via the {% debug %} tag. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website.
Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.
