Vulnerability Details

CVEID:   CVE-2022-27780
DESCRIPTION:   cURL libcurl could allow a remote attacker to bypass security restrictions, caused by a flaw that wrongly accepts percent-encoded URL separators like '/' by the URL parser. By sending a specially-crafted host name in a URL, an attacker could exploit this vulnerability to bypass filters and checks for URL.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/226250 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-2022-27778
DESCRIPTION:   An unspecified error with removing wrong file when --no-clobber is used together with --remove-on-error option in cURL libcurl has an unknown impact and attack vector.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/226248 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-2022-27782
DESCRIPTION:   cURL libcurl could allow a remote attacker to bypass security restrictions, caused by an easy connection reuse flaw for TLS and SSH. By sending a specially-crafted request using the connections in a connection pool, an attacker could exploit this vulnerability to bypass access restrictions.
CVSS Base score: 9.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/226252 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-2022-30115
DESCRIPTION:   cURL libcurl could allow a remote attacker to obtain sensitive information, caused by a HSTS check bypass flaw. By sending a specially-crafted request using a host name in the an URL with a trailing dot, an attacker could exploit this vulnerability to obtain sensitive information over clear-text HTTP, and use this information to launch further attacks against the affected system.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/226253 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N)

CVEID:   CVE-2022-27779
DESCRIPTION:   cURL libcurl could allow a remote attacker to bypass security restrictions, caused by a flaw that wrongly allows HTTP cookies to be set for Top Level Domains (TLDs). By using a specially-crafted host name with a trailing dot, an attacker could exploit this vulnerability to allow arbitrary sites to set cookies that would get sent to a different and unrelated site or domain.
CVSS Base score: 9.1
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/226249 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N)

CVEID:   CVE-2022-27774
DESCRIPTION:   cURL libcurl could allow a remote attacker to obtain sensitive information, caused by a flaw in the "same host check" feature during a cross protocol redirects. By sending a specially-crafted request, an attacker could exploit this vulnerability to obtain credentials information, and use this information to launch further attacks against the affected system.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/225294 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N)
