CVE-2025-48219 (GCVE-0-2025-48219)

Vulnerability from cvelistv5 – Published: 2025-05-18 00:00 – Updated: 2025-05-19 20:06 Exclusively Hosted Service
VLAI?
Summary
O2 UK before 2025-05-19 allows subscribers to determine the Cell ID of other subscribers by initiating an IMS (IP Multimedia Subsystem) call and then reading the utran-cell-id-3gpp field of a Cellular-Network-Info SIP header, aka an ECI (E-UTRAN Cell Identity) leak. The Cell ID might be usable to identify a cell location via crowdsourced data, and might correspond to a small physical area (e.g., if the called party is in a city centre). Removal of the Cellular-Network-Info header is mentioned in section 4.4.19 of ETSI TS 124 229.
