Security Bulletin: Multiple vulnerabilities in software used in node.js affect Cloud Pak System

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.
