Security Bulletin
Summary
Multiple vulnerabilities found in follow-redirect, html-parse-stringify2, nth-check, pycrypto affect Cloud Pak System. IBM Cloud Pak System has addressed those vulnerabilities.
Vulnerability Details
CVEID: CVE-2021-23346
DESCRIPTION: Node.js html-parse-stringify and html-parse-stringify2 modules are vulnerable to a denial of service, caused by a regular expression denial of service (ReDoS). By sending a specially-crafted input, a remote attacker could exploit this vulnerability to cause the process to freeze, and results in a denial of service condition.
CVSS Base score: 5.9
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/197736 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H)
CVEID: CVE-2022-0536
DESCRIPTION: Node.js follow-redirects module could allow a remote authenticated attacker to obtain sensitive information, caused by a leakage of the Authorization header from the same hostname during HTTPS to HTTP redirection. By utilize man-in-the-middle attack techniques, an attacker could exploit this vulnerability to obtain Authorization header information, and use this information to launch further attacks against the affected system.
CVSS Base score: 2.6
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/219551 for the current score.
CVSS Vector: (CVSS:3.0/AV:A/AC:H/PR:L/UI:N/S:U/C:L/I:N/A:N)
CVEID: CVE-2022-0155
DESCRIPTION: follow-redirects could allow a remote attacker to obtain sensitive information, caused by an unauthorized actor. By sending a specially-crafted request, a remote authenticated attacker could exploit this vulnerability to obtain private personal information and use this information to launch further attacks against the affected system.
CVSS Base score: 8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/216974 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H)
CVEID: CVE-2018-6594
DESCRIPTION: PyCrypto could allow a remote attacker to obtain sensitive information, caused by the generation of weak ElGamal key parameters in the lib/Crypto/PublicKey/ElGamal.py. By reading ciphertext data, an attacker could exploit this vulnerability to obtain sensitive information.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/138678 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N)
CVEID: CVE-2013-1445
DESCRIPTION: PyCrypto could allow a remote attacker to obtain sensitive information, caused by a race condition in the Crypto.Random pseudo-random number generator (PRNG). An attacker could exploit this vulnerability using brute force techniques to discover cryptographic keys and other sensitive information.
CVSS Base score: 2.6
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/88132 for the current score.
CVSS Vector: (AV:N/AC:H/Au:N/C:P/I:N/A:N)
CVEID: CVE-2012-2417
DESCRIPTION: PyCrypto could provide weaker than expected security, caused by an error when generating keys using the ElGamal scheme. A remote attacker could exploit this vulnerability using brute force techniques to derive the private key.
CVSS Base score: 4.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/75871 for the current score.
CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:P/A:N)
CVEID: CVE-2013-7459
DESCRIPTION: PyCrypto is vulnerable to a heap-based buffer overflow, caused by improper bounds checking by the ALGnew function in block_templace.c. By using a specially crafted iv parameter to cryptmsg.py, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.
CVSS Base score: 9.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/124083 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-2021-3803
DESCRIPTION: nth-check is vulnerable to a denial of service, caused by a regular expression denial of service (ReDoS) flaw. By sending a specially-crafted regex input, a remote attacker could exploit this vulnerability to cause a denial of service condition.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/209593 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.
