Java 7 Update 80 Vulnerabilities ((free)) Jun 2026

— The only comprehensive fix is upgrading to a supported version of Java, such as Java 8 (LTS through 2030) , Java 11 (LTS) , or Java 17 (LTS) . The Wikipedia support roadmap makes clear that third-party vendors such as Azul and BellSoft provide extended support options.

Use the following matrix to decide:

– Though affecting Java 7 via common enterprise libraries, these RCE flaws demonstrated that even if the core JRE was “final,” the ecosystem remained dangerous. Attackers could chain these with older JRE bugs to achieve full system compromise. java 7 update 80 vulnerabilities

It remains vulnerable to legacy cryptographic attacks (such as POODLE, BEAST, or RC4 biases) if configured to communicate with older systems. Technical Impact on Enterprise Environments Compliance Failures

Run the Java 7u80 application inside a highly restricted Docker container. Run the container container process as a non-root user and use read-only filesystems to limit the damage a Remote Code Execution attack can cause. — The only comprehensive fix is upgrading to

Even Oracle's commercial extended support for Java 7 eventually ended in July 2022, marking the absolute end of the line for the platform. After July 2022, Oracle stopped providing any new patches, bug fixes, or security issue fixes for Java 7, even for paying customers. The only exceptions were highly restricted binaries made available solely for the purpose of running specific Oracle products like the E-Business Suite. Consequently, any system running Java 7 Update 80—or any other version 7 release—today contains the vulnerabilities that have been discovered and publicly disclosed over the past seven years, with no official patches available to fix them.

Running in a production environment introduces substantial security risks, as it is plagued by hundreds of known vulnerabilities that allow for remote code execution, data manipulation, and total system compromise. Released by Oracle in April 2015, Update 80 represents the final free public release of the Java 7 runtime environment. Attackers could chain these with older JRE bugs

| CVE ID | Description | Impact | |--------|-------------|--------| | | Apache Commons Collections deserialization gadget (used in many Java apps, but Java 7’s standard libraries + third‑party libs make exploitation trivial). | Unauthenticated RCE | | CVE-2016-0636 | Exploits JMX/MBean deserialization issues (affects Java 7 update 80). | RCE | | CVE-2017-5644 | Apache POI & Java serialization – allows remote attacker to execute arbitrary code via crafted serialized objects. | RCE | | CVE-2018-2826 (part of the Spring4Shell family) | Not in core Java, but Java 7’s reflection APIs and classloading issues are leveraged. Java 7 lacks newer security manager improvements. | RCE | | CVE-2019-2725 | Oracle WebLogic (runs on Java 7) – deserialization flaw. Java 7 update 80 is vulnerable. | RCE | | CVE-2020-1472 (ZeroLogon) | Affects Windows domain controllers, but Java 7 apps often authenticate via NTLM – the Java 7 implementation is unpatched, leading to escalation. | Privilege escalation | | CVE-2022-21349 (Java SE 7 – after EOL) | Deserialization in JNDI/RMI. No fix for Java 7. | RCE |

Ensure JMX and RMI ports are never exposed to the public internet, and force authentication/encryption on those endpoints if they must be used internally. Conclusion
