description

NetScaler ADC and NetScaler Gateway deployments using Email OTP authentication are affected by a memory overflow. An attacker able to interact with that authentication flow may trigger erroneous behavior or a denial of service.

Still under analysis: more detail becomes available as the pipeline runs.

mitigation

Upgrade NetScaler ADC to 14.1-73.57, 13.1-64.39, 14.1-73.58 FIPS, or 13.1-37.293 FIPS and NDcPP, as applicable; upgrade NetScaler Gateway to 14.1-73.57 or 13.1-64.39. Restrict access to Email OTP authentication endpoints until upgrades are complete.

fixed in 14.1-73.57, 13.1-64.39, 14.1-73.58 FIPS, 13.1-37.293 FIPs and NDcPP
