• Critical Log4j Vulnerabilities Affect Real Estate Software

17 December 2021

Critical vulnerabilities in open-source software pose potential risks for a wide range of businesses, governments and individuals.

Log4shell, the vulnerability within the widely-used logging tool Log4j, means that anyone who uses Log4j to catalogue activity in their software applications or online services is at risk.

In the case of real estate software and PropTech, this could mean sensitive data such as floorplans, occupancy or budget information open to nefarious sources.

Apple, Minecraft, IBM, Cisco, Google and Amazon all use Log4j, and the issue was initially disclosed on December 9, 2021.

The “Most Severe Computer Vulnerability in Years

The National Cyber Security Centre is calling Log4shell “potentially the most severe computer vulnerability in years.” They also state that, If left unfixed, attackers can break into systems, steal passwords and logins, extract data, and infect networks with malicious software.

Esri UK, who provides indoor mapping software for facilities managers, has informed their customers that they are actively investigating the impact of the Log4j 2 library critical vulnerabilities, as some Esri products contain this common logging tool.

Esri’s GIS mapping tool is used by organisations such as Oxford University, Westminster City Council and The British Red Cross.

Oracle, AWS and Cloudflare have all issued advice to their customers.
