Description

This security bulletin contains information about 11 secuirty vulnerabilities.


1) Resource exhaustion (CVE-ID: CVE-2021-35065)

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 when processing regular expressions. A remote attacker can trigger resource exhaustion and perform a regular expression denial of service (ReDoS) attack.


2) Resource exhaustion (CVE-ID: CVE-2021-44906)

The vulnerability allows a remote attacker to escalate privileges on the system.

The vulnerability exists due to application does not properly control consumption of internal resources. A remote attacker can trick the library into adding or modifying the properties of Object.prototype, using a constructor or __proto__ payload, resulting in prototype pollution and loss of confidentiality, availability, and integrity.


3) Incorrect Regular Expression (CVE-ID: CVE-2022-3517)

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 and perform regular expression denial of service (ReDos) attack.


4) Buffer overflow (CVE-ID: CVE-2022-4904)

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary error within the config_sortlist() function. A local user can trigger memory corruption and perform a denial of service (DoS) attack.


5) Prototype pollution (CVE-ID: CVE-2022-24999)

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

The vulnerability exists due to improper input validation. A remote attacker can send a specially crafted request and perform a denial of service (DoS) attack.



6) Inefficient Algorithmic Complexity (CVE-ID: CVE-2022-25881)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to regular expression denial of service that occurs when the server reads the cache policy from the request using this library. A remote unauthenticated attacker can send malicious request header values to the server and perform a denial of service attack.


7) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2022-35256)

The vulnerability allows a remote attacker to perform HTTP request smuggling attacks.

The vulnerability exists due to improper validation of HTTP 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.


8) Input validation error (CVE-ID: CVE-2022-38900)

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

The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.


9) Reliance on Reverse DNS Resolution for a Security-Critical Action (CVE-ID: CVE-2022-43548)

The vulnerability allows a remote attacker to perform DNS rebinding attacks.

The vulnerability exists due to improper validation of octal IP address within the Node.js rebinding protector for --inspec. A remote attacker can resolve the invalid octal address via DNS. When combined with an active --inspect session, such as when using VSCode, an attacker can perform DNS rebinding and execute arbitrary code in client's browser.


10) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2023-23918)

The vulnerability allows a remote user to bypass implemented security restrictions.

The vulnerability exists due to improperly imposed security restrictions within the process.mainModule.require() method. A remote user can access non authorized modules.


11) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2023-23920)

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

The vulnerability exists due to application insecurely loads ICU data through ICU_DATA environment variable with elevated privileges. A remote user can gain access to potentially sensitive information.
