Java 7 Update 80 Vulnerabilities -

Java 7u80 does not support TLS 1.3 natively and requires manual configuration adjustments to properly handle TLS 1.2 in various client scenarios. It remains vulnerable to older cryptographic attacks (like POODLE or SWEET32) depending on the cipher suites enabled.

A vulnerability related to the Java Cryptography Extension (JCE) that allows remote attackers to compromise confidentiality.

Oracle released Java 7 Update 80 in April 2015. It was not a feature release; it was a closing statement. Oracle had announced that April 2015 would mark the End of Public Updates for Java 7. This meant that 7u80 was the last time the general public would receive a security patch for the Java 7 runtime without purchasing expensive extended support contracts. java 7 update 80 vulnerabilities

Impact

| | Disclosed | Impact / Description | |---|---|---| | CVE-2020-14779 | October 2020 | Easily exploitable via Serialization component; could cause partial denial-of-service (CVSS 3.0 Base Score 5.3) | | CVE-2020-14781 | October 2020 | Affects the JNDI component; could enable unauthorized read access to Java data | | CVE-2020-27221 | October 2020 | Stack-based buffer overflow when the JVM or JNI natives convert UTF-8 characters; could lead to arbitrary code execution | | CVE-2020-2601 | January 2020 | Kerberos TGS security vulnerability affecting the Libraries component | | CVE-2020-14803 | October 2020 | Unspecified vulnerability in the Libraries component; could lead to unauthorized update, insert, or delete access |

Remote Code Execution is the most dangerous type of vulnerability. It allows an attacker to execute arbitrary commands on a server or client machine hosting Java 7u80, often without needing authentication. Java 7u80 does not support TLS 1

Java’s security "sandbox" is designed to prevent untrusted code from accessing local system resources. Update 80 contains known bypasses that allow malware to "escape" and gain full access to the file system and network.

These usually involve flaws in serialization, Reflection API bypasses, or memory corruption within the JVM fonts or graphics processing libraries. Oracle released Java 7 Update 80 in April 2015

Since Java 7 Update 80 is no longer receiving security patches, it is considered highly insecure for production environments. Over 260 Common Vulnerabilities and Exposures (CVEs)
