Description

This security bulletin contains information about 4 vulnerabilities.


1) Resource exhaustion (CVE-ID: CVE-2020-8116)

CWE-ID: CWE-400 - Resource exhaustion

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:P/U:Green


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

The vulnerability exists due to prototype pollution. A remote authenticated attacker can modify the prototype of a base object which can vary in severity depending on the implementation (DoS, access to sensitive data, RCE).


2) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2020-8201)

CWE-ID: CWE-444 - Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Amber


The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

Node.js < 12.18.4 and < 14.11 can be exploited to perform HTTP desync attacks and deliver malicious payloads to unsuspecting users. The payloads can be crafted by an attacker to hijack user sessions, poison cookies, perform clickjacking, and a multitude of other attacks depending on the architecture of the underlying system. The attack was possible due to a bug in processing of carrier-return symbols in the HTTP header names.


3) Buffer overflow (CVE-ID: CVE-2020-8252)

CWE-ID: CWE-120 - Buffer overflow

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber


The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

The vulnerability exists due to incorrect validation of realpath in libuv. The library incorrectly determines the buffer size, which can result in a buffer overflow if the resolved path is longer than 256 bytes. A remote attacker can pass an overly long path to the application that is using the library, trigger memory corruption and execute arbitrary code on the system.


4) Inclusion of Sensitive Information in Log Files (CVE-ID: CVE-2020-15095)

CWE-ID: CWE-532 - Information Exposure Through Log Files

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


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

The vulnerability exists due to NPM Cli stores sensitive information into log files and supports URLs like "://[[:]@][:][:][/]". A local user can redirect output of a log file to an external URL.
