NTP users are strongly urged to take immediate action to ensure that their NTP daemons are not susceptible to being used in distributed denial-of-service (DDoS) attacks. Please also take this opportunity to defeat denial-of-service attacks by implementing Ingress and Egress filtering through BCP38.

ntp-4.2.8p15 was released on 23 June 2020. It addresses 1 medium-severity security issue in ntpd, and provides 13 non-security bugfixes over 4.2.8p13.

Please see the NTP Security Notice for vulnerability and mitigation details.

• Example: %URLPARAM{"skin"}% returns print for a .../view/TWiki/VarURLPARAM?skin=print URL
• Notes:
  • URL parameters passed into HTML form fields must be entity ENCODEd.
  • Double quotes in URL parameters must be escaped when passed into other TWiki variables.
    Example: %SEARCH{ "%URLPARAM{ "search" encode="quotes" }%" noheader="on" }%
  • When used in a template topic, this variable will be expanded when the template is used to create a new topic. See TWikiTemplates#TemplateTopicsVars for details.
  • Watch out for TWiki internal parameters, such as rev, skin, template, topic, web; they have a special meaning in TWiki. Common parameters and view script specific parameters are documented at TWikiScripts.
  • If you have %URLPARAM{ in the value of a URL parameter, it will be modified to %<nop>URLPARAM{. This is to prevent an infinite loop during expansion.
  • There is a risk that this variable could be misused for cross-site scripting.
