The QCMAP_Web_CLIENT binary in the Qualcomm QCMAP software suite prior to versions released in October 2020 does not validate the return value of a strstr() or strchr() call in the Tokenizer() function. An attacker who invokes the web interface with a crafted URL can crash the process, causing denial of service. This version of QCMAP is used in many kinds of networking devices, primarily mobile hotspots and LTE routers.
Weakness
The product dereferences a pointer that it expects to be valid but is NULL.
