Description

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.

• CWE-122Heap-based Buffer OverflowA heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc().
• CWE-190Integer Overflow or WraparoundThe product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.
