CVE-2026-8037: Progress LoadMaster Command Injection Vulnerability

CISA Cybersecurity Advisories | August 7, 2026 5:30 pm IST | Known Exploited

CISA has added one new vulnerability to its Known Exploited Vulnerabilities (KEV) Catalog, based on evidence of active exploitation. CVE-2026-8037 Progress LoadMaster Command Injection Vulnerability This type of vulnerability is a frequent attack vector for malicious cyber actors and poses significant risks to the federal enterprise. Binding Operational Directive (BOD) 26-04: Prioritizing Security Updates Based on Risk establishes vulnerability management requirements for Federal Civilian Executive Branch (FCEB) agencies. BOD 26-04 reinforces the importance of the…

Why it matters: CISA Cybersecurity Advisories LoadMaster may let attacker-controlled input cross into an interpreter or executable path, which can turn a reachable application feature into data access or code execution.

What to verify: Confirm the vulnerable route and authentication state, deploy the fixed release, review suspicious parameters and child processes, and test authorization boundaries after patching.

CVE-2026-71956: D-Link DWR-M961 devices with hardware version C1 and software version 1.1.2_C1_202602110044 contain…

NIST National Vulnerability Database | August 8, 2026 11:46 pm IST | CRITICAL | CVSS 9.8

D-Link DWR-M961 devices with hardware version C1 and software version 1.1.2_C1_202602110044 contain a command injection vulnerability in the app.cgi interface. A remote attacker can inject arbitrary malicious commands into the netDig.ping.dst field, resulting in command execution with root privileges.

Why it matters: CVE-2026-71956 may let attacker-controlled input cross into an interpreter or executable path, which can turn a reachable application feature into data access or code execution.

CVE-2026-71957: D-Link DWR-M961 devices with hardware version C1 and software version 1.1.2_C1_202602110044 contain…

NIST National Vulnerability Database | August 8, 2026 11:46 pm IST | CRITICAL | CVSS 9.8

D-Link DWR-M961 devices with hardware version C1 and software version 1.1.2_C1_202602110044 contain a buffer overflow vulnerability in the app.cgi interface. A remote attacker can write an overly long string to the netAcc.addlist[].name field and execute arbitrary commands by crafting a specific payload, or cause the device to crash.

Why it matters: CVE-2026-71957 is a memory-safety issue whose practical impact depends on the reachable parser, process privileges, platform protections, and reliability of attacker-controlled input.

What to verify: Confirm the exact affected build and component exposure, update from the vendor channel, review crash and restart telemetry, and keep network containment in place until the fixed process is running.

CVE-2026-71958: D-Link DWR-M961 devices with hardware version C1 and software version 1.1.2_C1_202602110044 contain…

NIST National Vulnerability Database | August 8, 2026 11:46 pm IST | CRITICAL | CVSS 9.8

D-Link DWR-M961 devices with hardware version C1 and software version 1.1.2_C1_202602110044 contain a buffer overflow vulnerability in the quicksetup.cgi interface. A remote attacker can write overly long strings to the test4, ssid2, and username fields and execute arbitrary commands by crafting a specific payload, or cause the device to crash.

Why it matters: CVE-2026-71958 is a memory-safety issue whose practical impact depends on the reachable parser, process privileges, platform protections, and reliability of attacker-controlled input.

What to verify: Confirm the exact affected build and component exposure, update from the vendor channel, review crash and restart telemetry, and keep network containment in place until the fixed process is running.

CVE-2026-71944: D-Link DWR-M961 devices with hardware version C1 and firmware version before 1.1.5_C1_202607071108…

NIST National Vulnerability Database | August 8, 2026 10:46 pm IST | CRITICAL | CVSS 9.8

D-Link DWR-M961 devices with hardware version C1 and firmware version before 1.1.5_C1_202607071108 contain a command injection vulnerability in the /boafrm/formLtefotaUpgradeQuectel interface. A remote attacker can inject arbitrary malicious commands into the fota_url field, resulting in command execution with root privileges.

Why it matters: CVE-2026-71944 may control a traffic or administration path that other systems implicitly trust, making reachability and management-plane exposure more important than the headline score alone.

What to verify: Inventory affected models and firmware, close public administration paths, compare routes and configuration, inspect flow and DNS logs, and validate connectivity after the upgrade.
