e-municipality module: Incorrect Use of Privileged APIs
CVE-2023-6151 is a high-severity incorrect use of privileged apis vulnerability in e-municipality module from ESKOM Computer, with a CVSS 3.1 base score of 7.5 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 v.105 as the first without the flaw, so updating e-municipality module to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.6% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update e-municipality module to v.105 or a later version.
- Update E-belediye to 105 or a later version.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

The underlying weakness: Incorrect Use of Privileged APIs
The product does not conform to the API requirements for a function call that requires extra privileges. This could allow attackers to gain privileges by causing the function to be called incorrectly.
How developers prevent this class of flaw
- Before calling privileged APIs, always ensure that the assumptions made by the privileged code hold true prior to making the call.
- Know architecture and implementation weaknesses of the privileged APIs and make sure to account for these weaknesses before calling the privileged APIs to ensure that they can be called safely.
- If privileged APIs make certain assumptions about data, context or state validity that are passed by the caller, the calling code must ensure that these assumptions have been validated prior to making the call.
