Summary
Acunetix 360 detected that a weak nonce value used in CSP declaration.
Impact
An attacker can carry out a successful Cross-site Scripting attack by predicting a valid nonce by exploiting this weakness.
Remediation
The application must generate a fresh value for the nonce-value directive at random and independently each time it transmits a policy. The value should be at least 128 bits long and should be generated using a cryptographically secure random number generator.
