Preliminary research
Citrix NetScaler pre-auth command injection through privileged log processing (CVE-2026-88771)
AI-collected research leads through 3 October 2026, including bounded month-by-month reviews of selected social and community sources from January through September. Unranked, incomplete, not community-vetted, and subject to change.
Patch-diff analysis follows attacker-controlled NetScaler HTTP log fields through grep, sed and awk processing before a root-run Perl path interpolates them into backticks. The article demonstrates the resulting pre-authentication command execution and supplies a detection artifact generator.
