Security Bulletin
This security bulletin contains information about 9 vulnerabilities.
1) Raccoon attack
EUVDB-ID: #VU46573
Risk: Medium
CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2020-1968
CWE-ID:
CWE-200 - Information exposure
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a timing flaw in the TLS specification. A remote attacker can compute the pre-master secret in connections which have used a Diffie-Hellman (DH) based ciphersuite and eavesdrop on all encrypted communications sent over that TLS connection.
Note: The attack can only be exploited if an implementation re-uses a DH secret across multiple TLS connections.

CVE-ID: CVE-2020-8201
CWE-ID:
CWE-444 - Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling')
Exploit availability: No
DescriptionThe 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) Buffer overflow
EUVDB-ID: #VU47248
Risk: High
CVSSv3.1: 8.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2020-8252
CWE-ID:
CWE-120 - Buffer overflow
Exploit availability: No
DescriptionThe 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.

6) Improper Authorization
EUVDB-ID: #VU28537
Risk: Medium
CVSSv3.1: 5.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2020-8172
CWE-ID:
CWE-285 - Improper Authorization
Exploit availability: No
DescriptionThe 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.
