CVE-2023-26462
ThingsBoard 3.4.1 could allow a remote attacker to gain elevated privileges because hard-coded service credentials (usable for privilege escalation) are stored in an insecure format.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.13%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
ThingsBoard 3.4.1 could allow a remote attacker to gain elevated privileges because hard-coded service credentials (usable for privilege escalation) are stored in an insecure format. (To read this stored data, the attacker needs access to the application server or its source code.)
