Another month, another Citrix security crisis. On June 17, 2025, Citrix disclosed two new critical vulnerabilities in its NetScaler ADC and Gateway platforms.
- CVE-2025-5777 ("CitrixBleed 2"): A memory-read vulnerability that lets attackers steal session tokens and bypass MFA.
- CVE-2025-6543: An unauthenticated DoS flaw that can knock out production systems.
And it gets worse: it appears that the fix for CitrixBleed 2 breaks login flows for SAML, RADIUS, and MFA users unless you manually configure Content Security Policy (CSP) headers - creating workaround that reportedly is already disrupting enterprise environments.
It’s not just a bug. It’s a pivot point.
Why This Moment Matters
Citrix’s issues appear to have increased since it went private and laid off many of its crucial staff. The latest vulnerability is just the tip of the iceberg. Over the last 18 months, organizations began to evaluate their ADC strategies, due the:
- Forced shift to subscription-only licensing
- ADC+VDI bundling that complicates infrastructure and probably not needed for those that either don’t have VDI requirements or have other competitive solutions
- Price hikes of up to 300% depending on the solutions
- Deprioritized support for smaller enterprise customers
The bottom line? NetScaler has experienced critical failings. But there’s a clear, proven alternative - Radware Alteon.
