Description
This security bulletin contains information about 16 secuirty vulnerabilities.
1) 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.
2) 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.
3) 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.
4) 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.
5) 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.
6) 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.
7) 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.
8) Prototype pollution (CVE-ID: CVE-2022-21824)
The vulnerability allows a remote attacker to perform a denial of service attack.
The vulnerability exists due to the formatting logic of the console.table() function. A remote attacker can send a specially crafted request and assign an empty string to numerical keys of the object prototype.
9) 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.
10) 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.
11) 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.
12) Information disclosure (CVE-ID: CVE-2022-0235)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to the application follows the "Location" HTTP header redirect and passes authorization cookie to a third-party resource. A remote attacker can gain access to sensitive information.
13) 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.
14) Improper Certificate Validation (CVE-ID: CVE-2021-44533)
The vulnerability allows a remote attacker to perform spoofing attack.
The vulnerability exists due to improper validation of certificate subject and issuer fields. A remote attacker can create a certificate with specially crafted multi-value Relative Distinguished Names and perform spoofing attack.
15) Improper validation of certificate with host mismatch (CVE-ID: CVE-2021-44532)
The vulnerability allows a remote attacker to perform spoofing attack.
The vulnerability exists due to improper validation of certificates, when converting SANs (Subject Alternative Names) to a string format. A remote attacker can inject special characters into the string and perform spoofing attack.
16) Improper Certificate Validation (CVE-ID: CVE-2021-44531)
The vulnerability allows a remote attacker to perform spoofing attack.
The
vulnerability exists due to insufficient validation of URI Subject
Alternative Names. Node.js accepts arbitrary Subject Alternative Name
(SAN) types, unless a PKI
is specifically defined to use a particular SAN type. A remote attacker
can bypass name-constrained intermediates and perform spoofing attack.
