Oracle’s Java Cloud Service open to code execution hacks, researchers warn

Researchers have released technical details and attack code for 30 security issues affecting Oracle's Java Cloud Service. Some of the issues make it possible for attackers to read or modify users' sensitive data or to execute malicious code, the researchers warned.

Poland-based Security Explorations typically withholds such public airings until after any vulnerabilities have been fixed to prevent them from being exploited maliciously. The researchers broke from that tradition this week after Oracle representatives failed to resolve issues including bypasses of the Java security sandbox, bypasses of Java whitelisting rules, the use of shared WebLogic server administrator passwords, and the availability of plain-text use passwords stored in some systems.

"The company openly admits it cannot promise whether it will be communicating resolution of security vulnerabilities affecting their cloud data centers in the future," Adam Gowdiak, CEO of Security Explorations said. The security research firm is the same one that has discovered a host of extremely severe vulnerabilities in Oracle's Java software framework, some of which have been exploited in the wild to surreptitiously install malware on end-user computers.
