Note: The appletviewer is intended for development purposes only. The conversion of an applet to a Java Web Start application provides the ability to launch and update the resulting application without relying on a web browser See What is Java Web Start and how is it launched?

As with any complex system, many security problems have been discovered and fixed since Java was first released. Some of these like the Calendar serialization security bug persisted for many years with nobody being aware. Others have been discovered in use by malware in the wild. Some studies mention applets crashing the browser or overusing CPU resources but these are classified as nuisances and not as true security flaws.

However, unsigned applets may be involved in combined attacks that exploit a combination of multiple severe configuration errors in other parts of the system. An unsigned applet can also be more dangerous to run directly on the server where it is hosted because while code base allows it to talk with the server, running inside it can bypass the firewall.

Your Answer

An applet may also try DoS attacks on the server where it is hosted, but usually people who manage the web site also manage the applet, making this unreasonable. Communities may solve this problem via source code review or running applets on a dedicated domain. The unsigned applet can also try to download malware hosted on originating server. However it could only store such file into a temporary folder as it is transient data and has no means to complete the attack by executing it.

There were attempts to use applets for spreading Phoenix and Siberia exploits this way, [ citation needed ] but these exploits do not use Java internally and were also distributed in several other ways. A signed applet [32] contains a signature that the browser should verify through a remotely running, independent certificate authority server. Producing this signature involves specialized tools and interaction with the authority server maintainers. Once the signature is verified, and the user of the current machine also approves, a signed applet can get more rights, becoming equivalent to an ordinary standalone program.

The rationale is that the author of the applet is now known and will be responsible for any deliberate damage. However, this approach requires more responsibility from the user, deciding whom he or she trusts. The related concerns include a non-responsive authority server, wrong evaluation of the signer identity when issuing certificates, and known applet publishers still doing something that the user would not approve of. Hence signed applets that appeared from Java 1. Self-signed applets, which are applets signed by the developer themselves, may potentially pose a security risk; java plugins provide a warning when requesting authorization for a self-signed applet, as the function and safety of the applet is guaranteed only by the developer itself, and has not been independently confirmed.

Such self-signed certificates are usually only used during development prior to release where third-party confirmation of security is unimportant, but most applet developers will seek third-party signing to ensure that users trust the applet's safety.

Real World Applications of Java

Java security problems are not fundamentally different from similar problems of any client-side scripting platform [33] [ citation needed ]. In particular, all issues related to signed applets also apply to Microsoft ActiveX components. As of , self-signed and unsigned applets are no longer accepted by the commonly available Java plugins or Java Web Start.

Consequently, developers who wish to deploy Java applets have no alternative but to acquire trusted certificates from commercial sources. Alternative technologies exist for example, JavaScript that satisfy all or more of the scope of what is possible with an applet.

Of these, JavaScript is not always viewed as a competing replacement [ by whom? JavaFX is an extension of the Java platform and may also be viewed as an alternative.
