Redis is used by several components in IBM Cloud Pak for Multicloud Management Monitoring as an in-memory shared cache database. It is not exposed outside the cluster.
DESCRIPTION: Redis could allow a remote authenticated attacker to obtain sensitive information, caused by a flaw in the Lua Debugger. By sending specially-crafted requests, an attacker could exploit this vulnerability to read data beyond the actual buffer, and use this information to launch further attacks against the affected system.
CVSS Base score: 3.1
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/210726 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:N/A:N)
DESCRIPTION: Redis is vulnerable to a heap-based buffer overflow, caused by improper bounds checking. By executing specially-crafted Lua scripts, a remote authenticated attacker could overflow a buffer and execute arbitrary code on the system.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/210723 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H)
DESCRIPTION: Redis is vulnerable to a denial of service, caused by improper input validation. By sending specially-crafted Redis Standard Protocol (RESP) requests, a remote attacker could exploit this vulnerability to allocate significant amount of memory.
CVSS Base score: 7.5
