A vulnerability has been identified in SIMATIC CP 1543-1 (All versions < V2.0.28), SIPLUS NET CP 1543-1 (All versions < V2.0.28). Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable. Actively exploited in the wild (cisa kev) and EPSS exploitation probability 14.6%.
When decoding data out of a dataset encoded with the H5Z_NBIT decoding, the HDF5 1.8.16 library will fail to ensure that the precision is within the bounds of the size leading to arbitrary code. Rated high severity (CVSS 8.6), this vulnerability is no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
In the HDF5 1.8.16 library's failure to check if the number of dimensions for an array read from the file is within the bounds of the space allocated for it, a heap-based buffer overflow will occur,. Rated high severity (CVSS 8.6), this vulnerability is no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
The HDF5 1.8.16 library allocating space for the array using a value from the file has an impact within the loop for initializing said array allowing a value within the file to modify the loop's. Rated high severity (CVSS 8.6), this vulnerability is no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
The library's failure to check if certain message types support a particular flag, the HDF5 1.8.16 library will cast the structure to an alternative structure and then assign to fields that aren't. Rated high severity (CVSS 8.6), this vulnerability is no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
