If you manage databases for a living, last week was a wake-up call. At the Wiz zeroday.cloud event, security researchers using an AI tool called "Xint Code" dug deep into the codebases of PostgreSQL and MariaDB. What they found wasn't a new, sophisticated zero-day exploit cooked up by a nation-state, but something arguably worse: buffer overflow issues and missing validation bugs that have been sitting dormant for 20 years.
We are talking about high and critical-severity vulnerabilities—specifically, a heap buffer overflow in MariaDB’s JSON schema validation and a remote code execution (RCE) flaw in PostgreSQL’s pgcrypto extension. These aren't theoretical. They allow attackers to execute arbitrary code on your database servers.
For the IT manager or the MSP technician, this scenario triggers a very specific, visceral kind of panic. You aren't just worried about an exploit; you are worried about the operational nightmare of finding every single instance of PostgreSQL or MariaDB across your environment and patching them before the automated bots find them first.
The Problem: Why "Alerting" Doesn't Equal "Action"
Here is the reality for most IT operations teams today: You likely have a monitoring tool that pings your database servers to ensure they are "up." You might even have a vulnerability scanner that emails you a PDF once a week listing known CVEs. And separately, you have an RMM (Remote Monitoring and Management) tool to push patches and run scripts.
This is the classic "Tool Sprawl" trap, and it is deadly when 20-year-old bugs surface.
When the news drops about a critical RCE in PostgreSQL:
- The Delay: Your monitoring tool doesn't know the difference between a "safe" PostgreSQL version and a vulnerable one. It just sees a green light.
- The Manual Scramble: You or your techs have to log into the vulnerability scanner, export the list of affected assets, and then manually cross-reference that with your RMM inventory.
- The Context Switch: You log into your RMM, create a dynamic group for "PostgreSQL Servers," and hope your tagging is accurate.
- The Execution: You write a script or push an update, but you have no immediate feedback loop. You are essentially flying blind while the clock ticks on your exposure window.
The problem isn't that you lack data; it's that your data is siloed. The alert lives in one world, and the remediation capability lives in another. In that gap between discovery and patching is where breaches happen. For an MSP managing 50 clients, a manual process like this turns a single CVE into a weekend of overtime and SLA risks.
How AlertMonitor Solves This: Unified RMM for Instant Remediation
At AlertMonitor, we built our platform to destroy the gap between "seeing" a problem and "fixing" it. We don't just monitor your infrastructure; we give you the RMM teeth to bite back immediately.
When a CVE like the recent PostgreSQL or MariaDB bug drops, the AlertMonitor workflow changes the game:
- Single Pane of Glass: You don't need to check a separate scanner. Our integrated monitoring and asset inventory allows you to immediately query your environment for all devices running affected versions of PostgreSQL or MariaDB.
- Integrated RMM: You don't switch tabs. Right from the alert or the device list, you can initiate a remote session or execute a script across the entire group of vulnerable servers simultaneously.
- Real-Time Feedback: When you run a remediation script, the output doesn't disappear into a void. It feeds back into the AlertMonitor timeline. You see, in real-time, which servers were patched successfully and which ones failed—allowing you to iterate immediately without logging into five different dashboards.
This isn't just about convenience; it is about shrinking your Mean Time to Remediate (MTTR). With AlertMonitor, the transition from "We have a vulnerability" to "Vulnerability patched" happens in minutes, not days.
Practical Steps: Auditing and Patching with AlertMonitor
You don't need AI to find these bugs if you have a rigorous process to keep your stack updated. Below are practical scripts you can run today within the AlertMonitor RMM environment to audit your database versions and verify service status.
1. Check PostgreSQL Version on Linux
Use this Bash script to quickly identify which of your Linux servers are running an outdated version of PostgreSQL that might be vulnerable to the pgcrypto RCE.
#!/bin/bash
# Check installed PostgreSQL version
if command -v psql &> /dev/null; then
version=$(psql --version | awk '{print $3}')
echo "PostgreSQL version found: $version"
# Add logic here to compare against known vulnerable versions
else
echo "PostgreSQL is not installed or not in PATH."
fi
2. Verify MariaDB Service Status on Linux
After applying a patch for the JSON schema validation overflow, you need to ensure the service restarted correctly. This script checks the status.
#!/bin/bash
# Check MariaDB service status
service_name="mariadb"
if systemctl is-active --quiet "$service_name"; then
echo "Success: $service_name is running."
else
echo "Warning: $service_name is not running. Attempting restart..."
systemctl restart "$service_name"
fi
3. Windows PowerShell Audit for SQL Services
For environments running databases on Windows endpoints, this PowerShell snippet helps you quickly identify SQL-related services and their states.
# Get all SQL related services and their status
Get-Service | Where-Object {$_.Name -like "*SQL*" -or $_.DisplayName -like "*SQL*"} |
Select-Object Name, DisplayName, Status, StartType | Format-Table -AutoSize
Conclusion
The discovery of 20-year-old bugs in core database technology proves that visibility is never enough. You can have the best monitoring in the world, but if you cannot act on that data instantly, you are still vulnerable. By unifying your monitoring, helpdesk, and RMM capabilities in AlertMonitor, you ensure that when the next critical bug hits, your team is ready to patch it before the first support ticket even opens.
