Description
This security bulletin contains information about 8 secuirty vulnerabilities.
1) Inclusion of Sensitive Information in Log Files (CVE-ID: CVE-2020-15095)
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.
2) Improper Authorization (CVE-ID: CVE-2020-8172)
The vulnerability allows a remote attacker to bypass authorization process.
The
vulnerability exists due to TLS session reuse and host certificate
verification bypass, as the 'session' event can be emitted before the
'secureConnect' event in Node.js. The application agent performs https
session caching and an unauthorized connection can be established via
the cached session ticket and treated as authorized connection.
3) Buffer overflow (CVE-ID: CVE-2020-8174)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within napi_get_value_string_latin1(), napi_get_value_string_utf8(), or napi_get_value_string_utf16() functions. A remote attacker can create a specially crafted data to the application, trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
4) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2020-8201)
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.
5) Resource exhaustion (CVE-ID: CVE-2020-8251)
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
Node.js < 14.11.0 is vulnerable to HTTP denial of service (DoS) attacks based on delayed requests submission which can make the server unable to accept new connections.
6) Use-after-free (CVE-ID: CVE-2020-8265)
The vulnerability allows a remote attacker to perform a DoS attack..
The vulnerability exists due to a use-after-free error in TLSWrap within the TLS implementation. A remote attacker can send specially crafted data to the service and perform a denial of service (DoS) attack.
7) Resource management error (CVE-ID: CVE-2020-8277)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper management of internal resources within the application when processing a large number of DNS responses. A Node.js application that allows an attacker to trigger a DNS request
for a host of their choice could trigger a denial of service condition.
8) HTTP request smuggling (CVE-ID: CVE-2020-8287)
The vulnerability allows a remote attacker to preform 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.
