The OWASP Penetration Testing Checklist is aimed at delivering a baseline standard against which potential vendor solutions can be assessed to ensure that a prospective web application security testing provider delivers a service that is sufficient

On the 15th of July 2021 Umbraco and AppCheck released a Security Advisory to alert users of a vulnerability within the Umbraco Forms component that could be exploited to gain remote code execution on the affected system.

The OWASP Top 10 Privacy Risks list is an attempt to curate a completely neutral set of prioritised privacy risks for businesses to consider, as well as a recommended set of countermeasures for businesses to deploy against the occurrence of those risks.

Customers new to the AppCheck platform can often be surprised at the number of vulnerabilities that AppCheck highlights relating to transport encryption offered on their services – unencrypted (plaintext) services, web applications with vulnerable cipher suites, encryption libraries containing exploitable flaws, registration forms that email users passwords in clear text. The list of checks that AppCheck performs is extensive, and on a website that has not previously been covered by regular vulnerability scanning, the extent of encryption issues can be surprising

Security Issue:

Researchers at AppCheck have discovered a security issue within Umbraco Forms which could lead to a remote code execution attack and/or arbitrary file deletion. Umbraco are advising everyone be ready for a fix which is to be released 20th July at 7am UTC.

In this article we’ll take a look into what HTTP “verbs” or methods are, how each varies and works, and what the potential security risks are that should be considered with each. We’ll also see how vulnerability scanners such as AppCheck can automatically check for many of the potential vulnerabilities presented by webservers making use of these methods.
