CVE-2026-9586 | Sangoma Switchvox Unauthenticated SQL Injection Remote Code Execution Vulnerability

CVE-2026-9586, a critical unauthenticated SQL injection to RCE in Sangoma Switchvox, is being actively exploited against internet-facing systems per honeypot observations.

CVE-2026-9586 (CVSS 4.0: 9.3) is an unauthenticated SQL injection in the /pa endpoint of Sangoma Switchvox SMB Edition, where the unsanitized PhoneIP value in XML phone notification requests reaches the PostgreSQL database. Horizon3 demonstrated escalation to OS command execution, and honeypots run with Defused Cyber observed exploitation attempts on August 30, 2026, using PostgreSQL commands with nc and curl. Fixed in Switchvox 8.4.0.2 released July 14, 2026; one attacker IP (176.65.148.184) was documented.

CISA Warns of Microsoft SQL Server RCE Vulnerability Exploited in Attacks

CISA warns attackers are exploiting CVE-2019-1068, a remote code execution vulnerability in Microsoft SQL Server, to run malicious commands on database servers.

CISA warned that CVE-2019-1068, a remote code execution vulnerability in Microsoft SQL Server, is being exploited in active attacks. Successful exploitation allows an attacker to execute malicious commands on a vulnerable database server, with access limited to the privileges of the SQL Server service account. The warning signals active exploitation of a long-known flaw and makes patching a priority for organizations running affected SQL Server deployments.

CISA added six actively exploited flaws to KEV, led by Citrix NetScaler CVE-2026-8452, with federal patch deadlines set.

CISA added six flaws to the KEV catalog on August 27, 2026, citing evidence of active exploitation, led by CVE-2026-8452, an improper buffer restriction in Citrix NetScaler ADC and Gateway that can cause denial-of-service. Defused Cyber and Previdian reported active exploitation of CVE-2026-8452, with 36 attempts over 12 days from 12 attacker IPs deploying web shells x.php and z.php. The other additions cover SQL Server RCE (CVE-2019-1068), Linux kernel out-of-bounds write (CVE-2022-0995), Red Hat ABRT and libuser privilege escalations (CVE-2015-5287, CVE-2015-3246), and AjaxPro deserialization RCE (CVE-2021-23758). FCEB agencies must patch CVE-2019-1068 and CVE-2026-8452 by August 29, 2026, and the rest by September 9, 2026.

CVE-2019-1068: A remote code execution vulnerability exists in ...

CISA added CVE-2019-1068, a high-severity remote code execution flaw in Microsoft SQL Server, to its KEV catalog after confirming exploitation in the wild.

CVE-2019-1068 (CVSS 8.8, CWE-20) is an improper input validation flaw allowing unauthenticated RCE in Microsoft SQL Server 2014 SP2/SP3, 2016, and 2017 on 32-bit and x64 builds. Exploitation requires low complexity and low privileges with no user interaction, and CISA formally added it to the KEV catalog on August 26, 2026. The CVE was originally published on July 15, 2019 and carries an EPSS score of 52.8%. Administrators must inventory affected SQL Server assets and apply vendor patches on an accelerated timeline.

Attackers Exploit Critical Switchvox Flaw to Deploy Reverse Shells Without Credentials

Attackers exploit unauthenticated SQL injection CVE-2026-9586 in Sangoma Switchvox to run PostgreSQL commands and deploy reverse shells.

Threat actors are exploiting CVE-2026-9586 (CVSS 9.3), an unauthenticated SQL injection in Sangoma Switchvox SMB Edition 8.3 (104997), since August 30, 2026, running arbitrary SQL as the PostgreSQL superuser and achieving remote code execution. The /pa endpoint concatenates the user-controlled PhoneIP value into PostgreSQL queries; attackers can extract database contents, escalate to Switchvox web administrator, exfiltrate the cookie signing key to forge authentication, and invoke reverse shells. Sangoma patched the flaw in Switchvox 8.4.0.2 on July 14, 2026, roughly 4,000 instances are internet-exposed (mostly in the US), and honeypot activity from IP 176.65.148.184 deploys reverse shells followed by Base64-encoded process enumeration.

U.S. CISA adds Metabase, Windows, and Cisco Secure Firewall flaws to its Known Exploited Vulnerabilities catalog.

CISA adds three actively exploited flaws—Cisco ASA/FTD DoS, Windows Winsock SYSTEM-level UAF, and Metabase SQL injection—to its Known Exploited Vulnerabilities catalog.

CISA added CVE-2026-20349 (CVSS 8.6, heap inspection flaw crashing Cisco ASA/FTD via crafted HTTP requests to the Remote Access SSL VPN service), CVE-2026-68820 (CVSS 7.0, use-after-free in the Windows afd.sys Winsock driver allowing SYSTEM-privilege code execution, actively exploited per Microsoft) and CVE-2026-72898 (CVSS 10.0, unauthenticated SQL injection in Metabase) to the KEV catalog. Metabase disclosed its cloud service was attacked with the 0-day, giving the intruder a path to administrator rights and stored credentials for connected databases; cloud instances were patched while self-hosted deployments need urgent updates. Under BOD 22-01, federal civilian agencies must patch by August 14, 2026, except CVE-2026-68820, due August 25.

GeoServer Zero-Day Is Already Being Probed. That’s the Problem

Unpatched GeoServer zero-day enabling SQL injection and possible RCE is being actively probed across exposed systems.

A zero-day in GeoServer's jsonArrayContains functionality allows unauthorized SQL injection and, in some configurations, remote code execution. Disclosed on August 12, 2026 without a CVE ID, it drew hundreds of exploitation probes from watchTowr within hours. No patch is available yet; GeoServer was previously mass-exploited via CVE-2024-36401.
