CVE-2019-5307 describes a message replay vulnerability affecting Huawei P30 and P30 Pro devices running specific firmware versions. Due to a less strict check on the NAS message sequence number (NAS COUNT), an attacker can establish a rogue base station. This allows them to replay GUTI reallocation commands to tamper with GUTIs or replay Identity request messages to obtain IMSIs. The vulnerability has a CVSS score of 4.2 (MEDIUM), indicating a low-impact attack with high complexity, requiring adjacent network access and no user interaction. Potential impacts include limited confidentiality and integrity compromise. Currently, there is no evidence of active exploitation, and no public exploit code (Metasploit, Nuclei, ExploitDB) is available. Community discussion and media coverage for this CVE are minimal.
