Am I affected?

Check the version of ipTIME T5008 you are running and compare it against the Affected row above (ipTIME T5008 0 to <=15.26.8; ipTIME AX2004M 0 to <=15.26.8; ipTIME AX3000Q 0 to <=15.26.8; ipTIME AX6000M 0 to <=15.26.8). If your build sits inside the affected range, you must patch.

Run the version check that fits your platform:


# Linux package check
dpkg -s iptime-t5008 2>/dev/null | grep -i ^Version
rpm -q iptime-t5008 2>/dev/null
command -v iptime-t5008 >/dev/null && iptime-t5008 --version 2>/dev/null


# Windows (PowerShell)
Get-Package -Name "*ipTIME T5008*" -ErrorAction SilentlyContinue | Select-Object Name, Version

If you can't patch immediately

Apply at least one of the following inline controls until you can deploy the patched build. None replace the upgrade.

Restrict exposure with nftables (Linux)


# Allow only trusted CIDR to reach the affected service ports
sudo nft add table inet filter 2>/dev/null || true
sudo nft 'add chain inet filter input { type filter hook input priority 0 ; }' 2>/dev/null || true
sudo nft 'add rule inet filter input tcp dport {80, 443} ip saddr != 10.0.0.0/8 drop'
sudo nft list ruleset

Block at the host firewall (Windows)


New-NetFirewallRule -DisplayName "Block-CVE-2026-24498" -Direction Inbound -Action Block -Protocol TCP -LocalPort 80,443 -RemoteAddress Any -Enabled True
Get-NetFirewallRule -DisplayName "Block-CVE-2026-24498"

Disable the affected service (Linux)


sudo systemctl stop iptime-t5008 2>/dev/null || true
sudo systemctl disable iptime-t5008 2>/dev/null || true

If the vendor advisory lists an official workaround, prefer that wording verbatim. If no workaround is published, the only safe remediation is the patch.

How to verify the fix worked

After upgrading, confirm the installed version matches the patched build and that no old library is still loaded by a long-running process.


# Linux
dpkg -s iptime-t5008 2>/dev/null | grep -i ^Version
rpm -q iptime-t5008 2>/dev/null || true
# Pid map check for old library handles
sudo lsof +c0 2>/dev/null | grep -i "DEL.*lib" || true


# Windows
Get-Package -Name "*ipTIME T5008*" | Select-Object Name, Version
Get-HotFix | Sort-Object InstalledOn -Descending | Select-Object -First 5

Expected: the reported version is at or above ipTIME AX2004M 15.27.2; ipTIME AX3000Q 15.27.2; ipTIME AX6000M 15.27.2; ipTIME T5008 15.27.2. Restart the affected service (systemctl restart <service> on Linux, or restart the Windows service) so it loads the patched binary.

Is CVE-2026-24498 actively exploited?

There is no public confirmation of exploitation in the wild listed in CISA KEV at the time of this writing. Patch anyway. Public exploits commonly follow disclosure within weeks.

Do I need to reboot after patching CVE-2026-24498?

For kernel and OS-level updates, yes. For most userland packages a systemctl restart <service> is enough on Linux, and restarting the Windows service or app on Windows. Any process that loaded the old library keeps using it until restarted.
