Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
EVerest is an EV charging software stack. An integer overflow in the "v2g_incoming_v2gtp" function in the v2g_server.cpp implementation can allow a remote attacker to overflow the process' heap. This vulnerability is fixed in 2024.3.1 and 2024.6.0.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

How this class of weakness works · CWE-122

Data overflows a buffer allocated on the heap, corrupting neighbouring heap structures and allocator metadata that a patient attacker can groom into control of execution. It is subtler than a stack overflow but just as dangerous. The fix is validating lengths before every write and using safe allocators and bounded operations.

Recommended fix High confidence

2024.3.1 or 2024.6.0

  1. 1. Identify the current version of EVerest/everest-core being used in your deployment
  2. 2. If running a version prior to 2024.3.1 or 2024.6.0, plan for an upgrade to version 2024.3.1 or 2024.6.0
  3. 3. Review the EVerest release notes and changelog for version 2024.3.1 and 2024.6.0 to understand included changes
  4. 4. Pull the updated everest-core container images or source code for the chosen fixed version
  5. 5. Test the upgrade in a non-production environment to verify compatibility with your deployment
  6. 6. Deploy the upgraded version to production after successful testing
