Vulnerability Details
CVEID: CVE-2020-8172
DESCRIPTION: Node.js could allow a remote attacker to bypass security restrictions. The 'session' event could be emitted before the 'secureConnect' event and possibly allow for the reuse of the TLS session. An attacker could exploit this vulnerability to bypass host certificate verification and gain access to the system.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/182814 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N)
CVEID: CVE-2020-8174
DESCRIPTION: Node.js is vulnerable to a buffer overflow, caused by multiple memory corruptions in the napi_get_value_string_latin1(), napi_get_value_string_utf8(), or napi_get_value_string_utf16() functions. By sending an overly long string, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause a denial of service.
CVSS Base score: 9.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/182816 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)
CVEID: CVE-2020-11080
DESCRIPTION: Node.js is vulnerable to a denial of service, caused by an error in the HTTP/2 session frame which is limited to 32 settings by default. By sending overly large HTTP/2 SETTINGS frames, an attacker could exploit this vulnerability to consume all available CPU resources.
CVSS Base score: 3.7
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/182815 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L)
