Security Bulletin
Summary
libcURL vulnerabilities were disclosed by the libcURL Project. libcURL is used by IBM Rational ClearCase. IBM Rational ClearCase has addressed the applicable CVEs.
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.

Disclaimer
According to the Forum of Incident Response and Security Teams (FIRST), the Common Vulnerability Scoring System (CVSS) is an "industry open standard designed to convey vulnerability severity and help to determine urgency and priority of response." IBM PROVIDES THE CVSS SCORES ""AS IS"" WITHOUT WARRANTY OF ANY KIND, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. CUSTOMERS ARE RESPONSIBLE FOR ASSESSING THE IMPACT OF ANY ACTUAL OR POTENTIAL SECURITY VULNERABILITY. In addition to other efforts to address potential vulnerabilities, IBM periodically updates the record of components contained in our product offerings. As part of that effort, if IBM identifies previously unidentified packages in a product/service inventory, we address relevant vulnerabilities regardless of CVE date. Inclusion of an older CVEID does not demonstrate that the referenced product has been used by IBM since that date, nor that IBM was aware of a vulnerability as of that date. We are making clients aware of relevant vulnerabilities as we become aware of them. "Affected Products and Versions" referenced in IBM Security Bulletins are intended to be only products and versions that are supported by IBM and have not passed their end-of-support or warranty date. Thus, failure to reference unsupported or extended-support products and versions in this Security Bulletin does not constitute a determination by IBM that they are unaffected by the vulnerability. Reference to one or more unsupported versions in this Security Bulletin shall not create an obligation for IBM to provide fixes for any unsupported or extended-support products or versions.
