Your patch management process probably assumes you have time. Time to test, schedule maintenance, and coordinate with vendors. That assumption falls apart when a critical vulnerability hits your infrastructure and threat actors start exploiting it within 48 hours of public disclosure.
The recent exploitation of CVE-2026-102255 in SonicWall SMA 1000 appliances tells a familiar story with an uncomfortable timeline: patches released October 6, exploitation attempts detected October 8, 135 recorded attempts from two U.S.-based IP addresses, and still no advisory update from the vendor acknowledging active exploitation. If you're a business continuity manager, this gap between patch availability and organizational action is where your continuity plans fail.
These myths about vulnerability management persist because they let organizations maintain comfortable timelines that don't match adversary behavior. Let's examine what's actually true.
Myth 1: "Critical vulnerabilities need testing before deployment"
Reality: A CVSS 10.0 pre-authenticated server-side request forgery doesn't need a three-week test cycle. CVE-2026-102255 allows remote attackers to direct the appliance to issue requests on their behalf, reach internal functionality, and perform unauthorized operations without authentication. There's no nuanced risk calculation here.
Your standard change control process assumes you're balancing operational stability against theoretical risk. But when exploitation attempts begin within 48 hours of patch release, you're balancing operational stability against active compromise. The SonicWall case shows 135 exploitation attempts before most organizations would have completed their testing protocols.
What you actually need: a tiered patching protocol that routes CVSS 9.0+ vulnerabilities with known exploitation directly to emergency change control, not standard change advisory boards. Your testing for these patches should focus on "does it break authentication or connectivity" rather than comprehensive regression testing.
Myth 2: "We'll know when exploitation starts because vendors update their advisories"
Reality: SonicWall released patches on October 6 and had not updated their advisory to reflect active exploitation as of the source reporting date, despite threat intelligence firms detecting attempts on October 8. You cannot wait for vendor acknowledgment to trigger your response.
Threat intelligence feeds from firms like Previdian and Defused Cyber detected exploitation before the vendor updated public guidance. This isn't vendor negligence; it's the reality that advisory updates follow internal verification processes while exploitation happens in real time.
Build your vulnerability response around threat intelligence integration, not vendor advisory monitoring. If you're relying solely on vendor security bulletins to understand exploitation status, you're operating with a 48-to-72-hour information gap that adversaries are already inside.
Myth 3: "Our vulnerability scanner will tell us if we're affected"
Reality: Your vulnerability scanner runs on a schedule. CVE-2026-102255 affects SonicWall SMA 1000 appliances, which sit at your network perimeter handling remote access. By the time your weekly or monthly scan identifies the vulnerability, you've given attackers weeks of opportunity against an internet-facing authentication gateway.
The SMA 1000 exploitation pattern from June 2026 shows what happens during that window: threat actors deployed Java web shells, installed KNUCKLEBALL malware, extracted credentials, harvested active session databases, and captured Time-Based One-Time Password MFA seed configurations. Then they pivoted into internal networks using the compromised appliance as a trusted initial access vector.
Your asset inventory should flag any internet-facing authentication or VPN appliance for immediate manual verification when critical vulnerabilities are disclosed. Don't wait for the scanner to catch up.
Myth 4: "We patched, so we're protected"
Reality: Patching closes the vulnerability; it doesn't address what happened before you patched. The SMA 1000 case from June 2026 demonstrates the persistence problem: threat actors established footholds, extracted high-value credentials, and configured long-term access before organizations even knew exploitation was occurring.
If you had vulnerable SMA 1000 appliances exposed between October 6 (patch release) and your actual patching date, you need to assume compromise and verify trust. That means credential rotation for any accounts accessible through the appliance, session invalidation, MFA seed regeneration, and forensic review of appliance logs for unauthorized operations.
Your patch deployment checklist should include post-patch verification steps specifically for authentication infrastructure: forced password resets for remote access accounts, MFA re-enrollment, review of recent access logs for anomalous sessions, and validation that no unauthorized changes were made to appliance configurations.
Myth 5: "This is an IT security problem, not a business continuity concern"
Reality: When threat actors compromise your remote access infrastructure, extract credentials, and pivot into your internal network, you're facing a business continuity event. The SMA 1000 exploitation chain leads directly to the scenarios your continuity plans address: unauthorized access to critical systems, potential data exfiltration, and the need to rebuild trust in authentication infrastructure.
Your continuity planning should explicitly account for authentication infrastructure compromise. What's your procedure when you can't trust your VPN? How do you maintain remote workforce access while rotating credentials and re-establishing trust? Which business functions depend on the compromised access path, and what's your alternative?
This isn't theoretical. The June 2026 SMA 1000 exploitation by threat actor UTA0533 created exactly this scenario: organizations had to assume their remote access gateway was compromised, their credentials were harvested, and their MFA seeds were captured, all while maintaining business operations.
What to Do Instead
Start with asset classification that treats internet-facing authentication infrastructure as critical continuity dependencies. Your SMA appliances, VPN concentrators, and remote access gateways aren't just security tools; they're single points of failure for remote workforce access.
Build a 24-hour patch deployment capability for CVSS 9.0+ vulnerabilities affecting these assets. This doesn't mean you patch everything in 24 hours; it means you can execute emergency patching when exploitation is detected or when the vulnerability allows pre-authenticated remote access to authentication infrastructure.
Integrate threat intelligence feeds that provide exploitation detection before vendor advisory updates. You need visibility into active exploitation attempts, not just CVE publication dates.
Create post-patch verification procedures for authentication infrastructure that assume compromise until you verify otherwise. Credential rotation, session invalidation, and forensic review should be standard follow-up, not optional extras.
Your business continuity plans should include procedures for operating when you can't trust your primary remote access path. What's your alternative authentication method? How do you maintain critical remote access while rebuilding trust in compromised infrastructure?
The gap between patch availability and patch deployment is where exploitation happens. The SonicWall case gives you the timeline: 48 hours from patch to active exploitation, 135 attempts while organizations were still scheduling maintenance windows. Your continuity planning needs to account for that reality.
