Description
This security bulletin contains information about 7 secuirty vulnerabilities.
1) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2021-22959)
The vulnerability allows a remote attacker to preform HTTP request smuggling attacks.
The vulnerability exists due to improper validation of HTTP requests, where the application accepts requests with a space right after the header name before the colon. A remote attacker can send a specially crafted HTTP request to the server and smuggle arbitrary HTTP headers.
Successful exploitation of vulnerability may allow an attacker to poison HTTP cache and perform phishing attacks.
2) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2021-22960)
The vulnerability allows a remote attacker to preform HTTP request smuggling attacks.
The vulnerability exists due to improper validation of HTTP requests, where the application ignores chunk extensions when parsing the body of chunked requests. A remote attacker can send a specially crafted HTTP request to the server and smuggle arbitrary HTTP headers.
Successful exploitation of vulnerability may allow an attacker to poison HTTP cache and perform phishing attacks.
3) Path traversal (CVE-ID: CVE-2021-37701)
The vulnerability allows a remote attacker to overwrite arbitrary files on the system.
The vulnerability exists due to input validation error when extracting tar files that contained both a directory and a symlink with
the same name as the directory, where the symlink and directory names in
the archive entry used backslashes as a path separator on posix
systems. A remote attacker can create a specially crafted archive and overwrite arbitrary files on the system.
4) Path traversal (CVE-ID: CVE-2021-37712)
The vulnerability allows a remote attacker to perform directory traversal attacks.
The vulnerability exists due to input validation error when extracting tar files that contained two directories and a symlink
with names containing unicode values that normalized to the same value. A remote attacker can create a specially crafted archive that, when extracted, can overwrite arbitrary files on the system.
5) Path traversal (CVE-ID: CVE-2021-37713)
The vulnerability allows a remote attacker to overwrite arbitrary files on the system.
The vulnerability exists due insufficient logic on Windows systems when extracting tar files that contained a path that
was not an absolute path, but specified a drive letter different from
the extraction target, such as C:some\path. If the drive letter does not match the extraction target, for example D:\extraction\dir, then the result of path.resolve(extractionDirectory, entryPath) would resolve against the current working directory on the C: drive, rather than the extraction target directory.
6) UNIX symbolic link following (CVE-ID: CVE-2021-39134)
The vulnerability allows a local attacker to escalate privileges on the system.
The vulnerability exists due to a symlink following issue. A local attacker can create a specially crafted symbolic link to a critical file on the system and overwrite it with privileges of the application.
Successful exploitation of this vulnerability may result in privilege escalation.
7) UNIX symbolic link following (CVE-ID: CVE-2021-39135)
The vulnerability allows a local attacker to escalate privileges on the system.
The vulnerability exists due to a symlink following issue. A local attacker can create a specially crafted symbolic link to a critical file on the system and overwrite it with privileges of the application.
Successful exploitation of this vulnerability may result in privilege escalation.
