Security Bulletin: Vulnerabilities in libcurl may affect IBM Spectrum Protect Plus (CVE-2021-22946, CVE-2022-27782, CVE-2022-27774, CVE-2022-22576, CVE-2021-22947, CVE-2022-27776)

Summary

Vulnerabilities in libcurl such as bypassing security restrictions, obtaining sensitive information, and man-in-the-middle attacks may affect IBM Spectrum Protect Plus.

Vulnerability Details

CVEID:CVE-2021-22946
**DESCRIPTION:**cURL libcurl could allow a remote attacker to obtain sensitive information, caused by a required TLS bypassed issue. By sniffing the network, an attacker could exploit this vulnerability to obtain sensitive data in clear text over the network, 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/209452 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-2022-27782
**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-2022-27774
**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)

CVEID:CVE-2022-22576
**DESCRIPTION:**cURL libcurl could allow a remote attacker to bypass security restrictions, caused by improper authentication validation when reuse OAUTH2-authenticated connections. By sending a specially-crafted request using user + “other OAUTH2 bearer”, an attacker could exploit this vulnerability to bypass access authentication validation.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/225291 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-2021-22947
**DESCRIPTION:**cURL libcurl is vulnerable to a man-in-the-middle attack, caused by a flaw when connecting to an IMAP, POP3, SMTP or FTP server to exchange data securely using STARTTLS to upgrade the connection to TLS level. An attacker could exploit this vulnerability to launch a man-in-the-middle attack and gain access to the communication channel between endpoints to obtain sensitive information or further compromise the system.
CVSS Base score: 7.4
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/209453 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N)

CVEID:CVE-2022-27776
**DESCRIPTION:**cURL libcurl could allow a remote attacker to obtain sensitive information, caused by a flaw when asked to send custom headers or cookies in its HTTP requests. By sending a specially-crafted request, an attacker could exploit this vulnerability to obtain authentication or cookie header data 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/225296 for the current score.
