CVE-2024-24260Public exploitNetwork attack vector

Service crash via freed subscription reference

Published Feb 5, 2024 · Updated Aug 26, 2024

Use-after-free in IReader media-server 1.0.0 allows remote attackers to crash a consuming service through SIP subscription removal. sip_subscribe_remove calls sip_subscribe_release, which frees the subscription object before an assertion reads subscribe->ref from that object. A consuming application must expose the affected SIP user-agent path; exploitation interrupts that process without reported data disclosure or modification.
