When it comes to open source libraries, DoS vulnerabilities allow attackers to trigger such a crash or crippling of the service by using a flaw either in the application code or from the use of open source libraries. One popular Denial of Service vulnerability is DDoS (a Distributed Denial of Service), an attack that attempts to clog network pipes to the system by generating a large volume of traffic from many machines. Rather, they are focused on making websites and services unavailable to genuine users resulting in downtime. Unlike other vulnerabilities, DoS attacks usually do not aim at breaching security. Detailsĭenial of Service (DoS) describes a family of attacks, all aimed at making a system inaccessible to its intended and legitimate users. The application may crash when the parsed HTML is either very deep or has a big amount of DOM elements. templates) where all your templates reside, using pug/jade( default and recommended by the email-templates) for this example await email.Html-to-text is an Advanced html to plain text converterĪffected versions of this package are vulnerable to Denial of Service (DoS).

ImplementationĬonst Email = require("email-templates") Ĭonst isLocal = _ENV = "development" Ĭonst = message Intentionally or unintentionally I would only need to view the final rendered email to verify mostly from, to, cc, subject, body and not the sending functionality, Then I put the pedal to the metal and explored ? email-templates and soon realized that we could easily cater to our needs without having to use the external tool at all. The problem is not to have our very own SMTP server.

Well, my approach to this problem started with the exploration of various tools for setting up the local mailer environment of sorts which would be ? free of cost.Ĭame across quite a few open source tools like mailcatcher, papercut, FakeSMTP to configure local SMTP Mail exchange server.Īfter a while, revisited the problem and felt that I overlooked the problem. What if ‘to’ recipient contains the CEO’s mail id…. What if ‘to’ recipient contains some team mailer group…. The situation still could be handled with peace when the victim is the colleague of yours
“Please ignore the last mail as it was by mistakenly sent during testing on local”
Then it could be possible that the developer needed to reply on the same email saying, 3 min read Preview email before actually sending them using Node.js Why does it matter to not send an email during development on local?Īt times, while doing development we tend to send an email intentionally or unintentionally to verify the email functionality for a specific feature which intern could lead to getting bombarded with testing emails which is of no use.
