Description

This security bulletin contains information about 8 secuirty vulnerabilities.


1) Incorrect Regular Expression (CVE-ID: CVE-2022-25883)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient input validation when processing regular expressions. A remote attacker can pass specially crafted data to the application via the new Range function and perform regular expression denial of service (ReDos) attack.


2) Prototype pollution (CVE-ID: CVE-2023-26136)

The vulnerability allows a remote attacker to execute arbitrary JavaScript code.

The vulnerability exists due to improper input validation. A remote attacker can pass specially crafted input to the application and perform prototype pollution, which can result in information disclosure or data manipulation.


3) UNIX symbolic link following (CVE-ID: CVE-2023-5115)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a symlink following issue. A local user can create a specially crafted symbolic link to files outside the application directory and overwrite them.


4) Improper Certificate Validation (CVE-ID: CVE-2023-29409)

The vulnerability allows a remote attacker to compromise the target system.

The vulnerability exists due to verifying certificate chains containing large RSA keys is slow. A remote attacker can cause a client/server to expend significant CPU time verifying signatures.


5) Resource exhaustion (CVE-ID: CVE-2023-39325)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to excessive consumption of internal resources when handling HTTP/2 requests. A remote attacker can bypass the http2.Server.MaxConcurrentStreams setting by creating new connections while the current connections are still being processed, trigger resource exhaustion and perform a denial of service (DoS) attack.


6) Cleartext transmission of sensitive information (CVE-ID: CVE-2023-40217)

The vulnerability allows a remote attacker to gain access to sensitive information.

The vulnerability exists due to an error in ssl.SSLSocket implementation when handling TLS client authentication. A remote attacker can trick the application to send data unencrypted.


7) Resource exhaustion (CVE-ID: CVE-2023-41164)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to application does not properly control consumption of internal resources within the django.utils.encoding.uri_to_iri() method. A remote attacker can pass a large number of characters to the affected method and perform a denial of service (DoS) attack.


8) Resource exhaustion (CVE-ID: CVE-2023-44487)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to improperly control of consumption for internal resources when handling HTTP/2 requests with compressed HEADERS frames. A remote attacker can send a sequence of compressed HEADERS frames followed by RST_STREAM frames and perform a denial of service (DoS) attack, a.k.a. "Rapid Reset".

Note, the vulnerability is being actively exploited in the wild.
