Same-Origin Policy (SOP) is a critical part of the security implemented within a web browser. It’s the part of your browser’s security system that prevents malicious pages from reading confidential information from other sites. So thepiratebay.com can’t read data from barclays.com because it’s blocked by SOP.
Criminals try to gather information about us online in order to scam us and steal our identities. In America in 2012, identity theft cost the average victim $365 and 12 hours of work to rectify. In 2013 there were 13.1 million U.S. adult victims, that’s nearly one victim every two seconds! That figure represents 5.5% of U.S. adults. This is why being savvy with our online privacy is important!
Got a path/directory traversal or file disclosure vulnerability on a Windows-server and need to know some interesting files to hunt for? I’ve got you covered Know any more good files to look for? Let me know! Are you on a Linux server? Try this one instead: Path Traversal Cheat Sheet: Linux
Struts is an extensible framework used for creating enterprise Java Web Applications. In Struts 1.x there is a problem related to how the ActionForm bean population machanism works, whereas in Struts 2.x there is an issue in how ParametersInterceptor allows access to the ‘class’ parameter that is directly mapped to the getClass() method and allows ClassLoader manipulation. Long story short, this can allow attackers to execute arbitrary Java code remotely.
Compression Ratio Info-leak Made Easy CRIME is an attack against SSL, like Heartbleed, but it has a much smaller probability of exploitation. The authors of CRIME also wrote the BEAST attack. The attack can allow an attacker to recover web cookies and thereby perform session hijacking attacks, much like BEAST and the specific restrictions for the attack are similar.
Browser Exploit Against SSL/TLS BEAST is an attack against SSL/TLS which is the cryptographic system that protects data sent online. A practical attack was found to be possible against TLS v1.0 and SSLv3.0 (and below). The issue is that the Initialisation Vector (IV) utilised as part of the encryption process can be determined by an attacker. IVs are utilised to prevent encrypted data from being deterministic, they essentially make it harder for attackers to determine patterns in encrypted data. Without them if a repeating pattern is evident in the plaintext then it will be evident in the ciphertext and this …
CVE-2014-0160 A vulnerability exists in outdated version of OpenSSL which allows an attacker to cause the server to disclose up to 64kb of server memory contents. This can cause secret keys, authentication tokens, usernames and passwords to be compromised. This can lead to an attacker being able to impersonate users and decrypt data transferred between a user and the server.
HSTS is a web security mechanism to prevent downgrade attacks, it’s a mechanism that allows a web server to instruct web browsers to only communicate with the server over SSL, so that all subsequent traffic is encrypted, even if a user attempts to visit an insecure link (the browser will ‘correct’ the user and request the secure site instead).
Got a path/directory traversal or file disclosure vulnerability on a Linux-server and need to know some interesting files to hunt for? I’ve got you covered Know any more good files to look for? Let me know! The list included below contains absolute file paths, remember if you have a traversal attack you can prefix these with encoding traversal strings, like these:
All the fun of the post on XML External Entities (XXE) but less wordy! A internal entity: <!–?xml version=”1.0″ ?–> <!DOCTYPE replace [<!ENTITY example “Doe”> ]> <userInfo> <firstName>John</firstName> <lastName>&example;</lastName> </userInfo>
