Executive Snapshot (Past ~24 Hours)

No new CISA KEV entries were added in the last 24 hours at publication time. The most recent KEV additions continue to be:
- CVE-2025-7775 — Citrix NetScaler ADC/Gateway memory overflow (RCE/DoS; exploited in the wild), added Aug 26. Patching is mandatory; KEV lists vendor/NVD references. CISA
- CVE-2025-48384 — Git link-following / submodule config handling flaw; inconsistent carriage-return handling can lead to dangerous misconfiguration paths; now in KEV with broad vendor advisories. CISA
Independent coverage within the last ~48 hours continues to highlight Citrix NetScaler CVE-2025-7775 as actively exploited and urgent, and Git CVE-2025-48384 as a serious supply-chain-adjacent risk. TechRadar+1

What this means for defenders today: Even when “new” KEV adds are quiet, exploitation does not pause. Use this daily to (1) confirm exposure, (2) prioritize patch/change windows, and (3) hunt for active abuse.

(Sections 3–4 are included because they remain top-priority in ongoing exploitation windows even if added to KEV a few days earlier. Patch windows are still open at most orgs.) CISA

1) Citrix NetScaler ADC & Gateway — CVE-2025-7775 (RCE/DoS)

Why it matters now: NetScaler sits on the edge—a compromise is a fast lane to domain access, session hijack, and ransomware detonation. KEV confirmed exploitation; external press and vendor analysis emphasize urgency. CISA TechRadar Tenable®

What it is: Memory overflow leading to remote code execution/DoS on NetScaler ADC/Gateway (Gateway/AAA vServers with specific IPv6 configs at risk). Citrix has released patched firmware; no work-around beats patching. TechRadar

KEV facts:

Date Added: 2025-08-26; Due Date (FCEB): 2025-08-28.
Action: Apply vendor mitigations or discontinue use if you cannot patch, per KEV. CISA

Risk posture:

Internet-exposed, high-value, often mis-segmented appliances.
Historically targeted by APTs and ransomware crews; earlier Citrix devices (e.g., 2023 CVE-2023-3519) were mass exploited. (Contextual history.)

What to do in the next 24 hours

Identify exposure: Inventory NetScaler ADC/Gateway; confirm if configured as Gateway/AAA vServers with IPv6.
Patch to fixed firmware immediately; reboot per vendor notes. CISA Tenable®
Harden:
- Geo/IP ACLs to admin interfaces
- Enforce MFA for admin; disable unused vServers
- Ensure logging to a SIEM with high-fidelity HTTP logs

Hunt queries (examples):

Look for sudden crashes/restarts of NetScaler processes, unexpected DoS spikes, or new/unknown admin sessions from rare geos.

2) Git — CVE-2025-48384 (Submodule link-following / CR handling)

Why it matters now: Git underpins source code supply chains. This flaw abuses carriage return handling within submodule configs to cause misconfig, potentially enabling code execution or repository poisoning paths in chained scenarios. KEV lists it, with vendor patches live; mainstream coverage warns strongly. CISA TechRadar

Impact snapshot: Projects that clone untrusted repos (or recursively clone submodules) risk unexpected configuration overrides and dangerous hook behavior if not controlled. Patches exist in Git 2.43.7 through 2.50.1 and across major distros. (See KEV refs to GitHub advisory / MSRC / Red Hat / AWS/Oracle Linux errata.) CISA

What to do in the next 24 hours

Patch Git everywhere (developer laptops, CI runners, build containers, agents).
Disable hooks by default via core.hooksPath in central templates; enforce no recursive submodule clones from untrusted repos. (Mitigations highlighted in press coverage.) TechRadar
Audit repos: Search for submodule entries containing control characters; enforce signed commits/tags and branch protections.

CI/CD checks:

Rebuild containers with patched git.
Validate that pipeline steps don’t perform implicit recursive clones.
Enforce git config --global protocol.file.allow never on runners where feasible.

3) Apple iOS/iPadOS/macOS — CVE-2025-43300 (Image I/O OOB Write)

Current relevance: A recent Apple zero-day fixed across platforms; KEV lists it with references to Apple support bulletins. Attackers often reverse patches to target laggards. If your fleet isn’t fully updated, treat as active exposure within your next 24-48 hours. CISA

Action now:

Push iOS/iPadOS/macOS updates organization-wide; MDM compliance to block outdated devices from enterprise apps.
Disable automatic image previewing in sensitive workflows where feasible (high-risk users).
Hunt for image-driven crashes and odd previewd processes following message/email ingestion.

4) Trend Micro Apex One — CVE-2025-54948 (Pre-auth OS Command Injection)

Why it stays on today’s list: Security console compromise = enterprise-wide blast radius. KEV flags this with vendor guidance. If your change freeze delayed patching, use the next 24 hours to finish remediation. CISA

Immediate tasks:

Patch the on-prem management console.
Restrict console to internal management VLAN, behind VPN + SSO/MFA.
Monitor for unexpected job deployments or script pushes to agents.

5) 24-Hour Patch & Configuration Priority Plan

Priority A (Internet-facing / actively exploited):

Citrix NetScaler (CVE-2025-7775) — patch firmware; lock admin and vServers; verify IPv6 exposure paths. CISA Tenable®
Git (CVE-2025-48384) — patch across developer endpoints and CI; audit submodules; disable hooks by default. CISA TechRadar

Priority B (High-impact endpoint/mobile):
3) Apple Image I/O (CVE-2025-43300) — force OS updates; enforce MDM compliance gates. CISA

Priority C (Enterprise security tooling consoles):
4) Trend Micro Apex One (CVE-2025-54948) — patch console; tighten network isolation. CISA

6) Detection & Threat Hunting Playbooks (Copy-paste Ready)

Note: Tailor index/field names to your SIEM. These samples are vendor-neutral to get teams started today.

6.1 Citrix NetScaler (CVE-2025-7775)

Goal: Find likely exploit traffic and post-exploitation pivots.

Indicators:
- Spikes in AAA/Gateway vServer errors or restarts
- Unfamiliar admin logins (new IP/ASN/country)
- Sudden config diffs or ns.conf changes
Generic SIEM search idea:
- Filter device logs for process restarts, crash signatures, or HTTP 5xx surges, grouped by /vpn/ or AAA endpoints.
- Cross-correlate admin logins and config change timestamps.
EDR hunt: Look for new binaries or reverse shells spawned by NetScaler processes; unusual /netscaler/ paths accessed externally.

6.2 Git (CVE-2025-48384)

Goal: Spot suspicious submodule activity / hook abuse.

Developer endpoints:
- Log all git clone + --recurse-submodules; alert on repos from unknown orgs.
- Alert on core.hooksPath modifications and unexpected hook executions.
CI/CD:
- Detect pipelines that dynamically fetch arbitrary submodules.
- Block control characters in .gitmodules via pre-merge checks.

6.3 Apple Image I/O (CVE-2025-43300)

MDM telemetry: Devices not on patched builds; block access to corporate apps.
Hunt: Image preview/parse process crashes (e.g., QuickLook, imagent) followed by persistence artifacts.

6.4 Trend Micro Apex One (CVE-2025-54948)

Console access logs: Pre-auth requests from rare IPs, odd admin job creation bursts.
Agent behavior: Wide, unscheduled policy/script pushes; lateral movement from console host.

7) Executive Risk Briefings — What to Say in the Boardroom Today

Theme: “Identity, edge, and supply chain remain the fastest breach paths.”

Cost of delay: For edge appliances (Citrix), hours matter. Earlier waves showed mass exploitation within 48–72 hours of public advisories. (Historical pattern guidance.)
Source control: The Git issue demonstrates how developer endpoints and CI are now prime breach pivots.
Mobile/Endpoint patching: The Apple Image I/O case reiterates that mobile zero-days keep attackers ahead; slow patch uptake widens the exposure window.

Decision asks (today):

Approve emergency Citrix change windows. CISA Tenable®
Mandate organization-wide Git upgrade + CI container rebuilds. CISA TechRadar
Enforce Apple OS compliance gates via MDM. CISA
Confirm Apex One console patch and network isolation. CISA

8) Service Desk & IT Ops Runbook (24-Hour Actions)

Citrix
- Back up configs → apply Citrix-recommended firmware → reboot → validate health.
- Disable/limit unused vServers; enforce MFA for GUI/SSH.

10) FAQs — Quick Answers for Stakeholders

Q: We patched Citrix—are we safe?
A: You’ve reduced risk, not eliminated it. Validate no persistence on adjacent hosts, review admin logs, and rotate credentials used on the appliance. Tenable®

Q: Our engineers use Git via platform GUIs—do we still need to patch local Git?
A: Yes. Developers often run local Git for tooling; unpatched clients + recursive submodules are a risk. Patching CI runners is equally critical. CISA TechRadar

Q: Apple devices auto-update… can we wait?
A: Auto-update lag + roaming users = long exposure windows. Enforce minimum OS versions in MDM to gate access to corporate apps. CISA

Q: Which CVEs are actually exploited today?
A: KEV catalogs known exploited vulns. As of this report, Citrix CVE-2025-7775 and Git CVE-2025-48384 remain highlighted with exploitation evidence and multi-vendor advisories. CISA TechRadar+1
