SB2020011452 - Multiple vulnerabilities in Oracle Communications Interactive Session Recorder

Description

This security bulletin contains information about 3 vulnerabilities.

1) Information disclosure (CVE-ID: CVE-2018-6829)

CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor

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

The vulnerability allows a remote unauthenticated attacker to obtain potentially sensitive information on the target system.

The weakness exists in the cipher/elgamal.c source code due to insufficient encryption. A remote attacker can access improperly coded plaintexts.

2) Security restrictions bypass (CVE-ID: CVE-2018-16395)

CWE-ID: CWE-20 - Improper input validation

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

The vulnerability allows a remote attacker to bypass security restrictions on the target system.

The weakness exists in OpenSSL::X509::Name due to the equality check is not correct if the value of an entity of the argument (right-hand side) starts with the value of the receiver (left-hand side). A remote attacker can supply malicious X.509 certificate to be passed and bypass security restrictions to conduct further attacks.

3) Prototype pollution (CVE-ID: CVE-2019-11358)

CWE-ID: CWE-1321 - Improperly Controlled Modification of Object Prototype Attributes (\'Prototype Pollution\')

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

The vulnerability allows a remote attacker to execute arbitrary JavaScript code.

The vulnerability exists due to improper input validation. A remote attacker can pass specially crafted input to the application and perform prototype pollution, which can result in information disclosure or data manipulation.
