CVE-2022-45876

Local file disclosure via ProjektInfo.XML entity expansion

Published Apr 26, 2023 · Updated Jan 17, 2025

XML external entity injection in VISAM VBASE before 11.7.5 allows remote attackers to read local data through a crafted project file. VBASE-Editor parses ProjektInfo.XML without restricting external entity references, causing an attacker-selected URI to be accessed and its contents embedded for further processing. Exploitation requires a valid user to open the file, and disclosure is limited to data accessible to the current process.
