Executive brief
A security flaw has been identified in the Huly Platform, an open-source process management and collaboration tool. An unauthorized user could potentially access sensitive mailbox secrets due to improper access controls within the system's internal communication interface. This could lead to the exposure of private communication credentials or other sensitive account data.
Technical details
An improper access control vulnerability (CWE-284/CWE-266) exists in the hcengineering Huly Platform up to version 0.7.0. The flaw is located in the 'getMailboxSecret' function within 'server/account/src/operations.ts', which is part of the RPC Interface component. A remote attacker with low-level privileges can exploit this vulnerability to bypass intended access restrictions and retrieve mailbox secrets. The attack vector is network-based and does not require user interaction, though it does require basic authentication (PR:L). Public exploit code is reportedly available, and as of the advisory date, no official patch has been confirmed by the vendor.
