CVE-2024-39527

Protected-file disclosure via crafted CLI commands

Published Oct 11, 2024 · Updated Oct 11, 2024

Information disclosure in Junos OS on SRX Series devices allows local users with low-privilege CLI access to read protected files. The CLI mishandles crafted commands by permitting a restricted login class to retrieve file-system content outside its authorized access. Exploitation requires an authenticated Junos CLI account, and exposed files can contain sensitive information usable for further system impact.
