When Open5GS UPF receives a PFCP Session Establishment Request, it stores related values for building the PFCP Session Establishment Response. Once UPF receives a request, it gets the f_teid_len from incoming message, and then uses it to copy data from incoming message to struct f_teid without checking the maximum length. If the pdi.local_f_teid.len exceeds the maximum length of the struct of f_teid, the memcpy() overwrites the fields (e.g., f_teid_len) after f_teid in the pdr struct. After parsing the request, the UPF starts to build a response. The f_teid_len with its overwritten value is used as a length for memcpy(). A segmentation fault occurs, as a result of a memcpy(), if this overwritten value is large enough.

ogs_fqdn_parse in Open5GS 1.0.0 through 2.3.3 inappropriately trusts a client-supplied length value, leading to a buffer overflow. The attacker can send a PFCP Session Establishment Request with "internet" as the PDI Network Instance. The first character is interpreted as a length value to be used in a memcpy call. The destination buffer is only 100 bytes long on the stack. Then, 'i' gets interpreted as 105 bytes to copy from the source buffer to the destination buffer.

A request-validation issue was discovered in Open5GS 2.1.3 through 2.2.x before 2.2.1. The WebUI component allows an unauthenticated user to use a crafted HTTP API request to create, read, update, or delete entries in the subscriber database. For example, new administrative users can be added. The issue occurs because Express is not set up to require authentication.
