Business Process Manangement (BPM): Improper Control of Generation of Code

Published Updated By the CyberSecBulletin desk

CVE-2024-5683 is a critical-severity improper control of generation of code vulnerability in Business Process Manangement (BPM) from Next4Biz CRM & BPM Software, with a CVSS 3.1 base score of 9.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 6.6.4.5 as the first without the flaw, so updating Business Process Manangement (BPM) to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.51% chance of exploitation within 30 days, which is low compared with other CVEs.

Critical severity: a successful attack would have severe impact.

What to do

  1. Update Business Process Manangement (BPM) to 6.6.4.5 or a later version.
  2. Update business_process_manangement to 6.6.4.5 or a later version.
  3. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description

The underlying weakness: Improper Control of Generation of Code

The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment.

How developers prevent this class of flaw

  • Refactor your program so that you do not have to dynamically generate code.
  • Run your code in a jail or similar sandbox environment that enforces strict boundaries between the process and the operating system. This may effectively restrict which code can be executed by your product. Examples include the Unix chroot jail and AppArmor. In general, managed code may provide some protection. This may not be a feasible solution, and it only limits the impact to the operating system; the rest of your application may still be subject to compromise. Be careful to avoid CWE-243 and other weaknesses related to jails.
  • Use dynamic tools and techniques that interact with the product using large test suites with many diverse inputs, such as fuzz testing (fuzzing), robustness testing, and fault injection. The product's operation may slow down, but it should not become unstable, crash, or generate incorrect results.
