Security Bulletin: Multiple security vulnerabilities in Redis may affect IBM Robotic Process Automation for Cloud Pak

Summary

Redis is used by IBM Robotic Process Automation for Cloud Pak as part of the server component. (CVE-2022-35977, CVE-2022-36021, CVE-2023-25155, CVE-2023-28856).

Vulnerability Details

CVEID:CVE-2022-35977
**DESCRIPTION:**Redis is vulnerable to a denial of service, caused by an integer overflow flaw. By sending specially-crafted SETRANGE and SORT(_RO) commands, a local authenticated attacker could exploit this vulnerability to allocate impossible amounts of memory and abort with an OOM panic.
CVSS Base score: 5.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/245141 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H)

CVEID:CVE-2022-36021
**DESCRIPTION:**Redis is vulnerable to a denial of service, caused by a flaw in the string pattern matching functionality. By using the string matching commands (such as SCAN or KEYS) with a specially-crafted pattern, a local authenticated attacker could exploit this vulnerability to cause a denial of service.
CVSS Base score: 5.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/248940 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H)

CVEID:CVE-2023-25155
**DESCRIPTION:**Redis is vulnerable to a denial of service, caused by an integer overflow. By sending a specially-crafted SRANDMEMBER, ZRANDMEMBER, and HRANDFIELD command, a remote authenticated attacker could exploit this vulnerability to cause a runtime assertion and termination of the Redis server process.
CVSS Base score: 5.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/248873 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H)

CVEID:CVE-2023-28856
**DESCRIPTION:**Redis is vulnerable to a denial of service, caused by improper input validation. By sending a specially crafted HINCRBYFLOAT command, a local authenticated attacker could exploit this vulnerability to cause the redis-server process to crash.
CVSS Base score: 5.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/253237 for the current score.
