Exploitation of Sangoma Switchvox flaw is underway (CVE-2026-9586)

Attackers actively exploit SQL injection flaw CVE-2026-9586 in unauthenticated Sangoma Switchvox endpoints, dropping reverse shells and second-stage cryptominer malware.

CVE-2026-9586, an unauthenticated SQL injection in Sangoma Switchvox SMB Edition 8.3, lets crafted HTTP POST requests execute arbitrary SQL against the backend PostgreSQL database. Horizon3 honeypots first saw exploitation on August 30, 2026 from IP 176.65.148.184, and dozens of additional source IPs have since joined with scanning payloads and second-stage malware that appears to be a cryptominer. The flaw was patched in Switchvox 8.4.0.2 on July 14, 2026; roughly 4,000 exposed instances exist, mostly in the United States, and exploitation is likely against most of them.

Exploring the Latest Mispadu Stealer Variant

Unit 42 found a new Mispadu infostealer variant targeting Mexican users via malicious .url files exploiting the SmartScreen CVE-2023-36025 bypass.

Unit 42 discovered a new variant of Mispadu Stealer, a Delphi-based banking trojan first reported in 2019, found while hunting for the Windows SmartScreen bypass CVE-2023-36025. The campaign uses crafted .url files referencing UNC network-share paths with an HTTP port (@80) that forces payload retrieval over WebDAV via rundll32.exe, avoiding SmartScreen warnings. Analyzed samples (~4 KB, compiled 2023-11-12) predate the CVE publication, and ZIP payloads were likely distributed as email attachments, primarily targeting users in Mexico.
