The device exposes a PC passthrough port and visible network settings like IP address and VLAN, raising concerns about whether the network has been properly segmented and locked down against unauthorized access via such old endpoints. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### Is the Cisco IP phone 7975 still a security risk even though it's end of life? Yes, unsupported end-of-life devices like the Cisco 7975 remain common in real environments, including hotels, and pose ongoing risk. The phone includes a rear port that lets someone plug in a PC and reach the network, so if the VLAN isn't restricted on that port, anyone with physical access could gain unauthorized network access. _Track overlooked hardware risks like unsupported VoIP phones with security-focused reading curated on daily.dev._ ## Similar posts on daily.dev - [I replaced my ISP router with used enterprise gear because the hardware was cheap](https://daily.dev/posts/i-replaced-my-isp-router-with-used-enterprise-gear-because-the-hardware-was-cheap-7fos4qg71) · XDA Developers · 1 upvotes · 0 comments - [Simplifying Conference Room Deployments with Catalyst 9200CX](https://daily.dev/posts/simplifying-conference-room-deployments-with-catalyst-9200cx-rd78gamb4) · Cisco · 0 upvotes · 0 comments - [Your old router is being rented to cybercriminals, and the FBI knows it](https://daily.dev/posts/your-old-router-is-being-rented-to-cybercriminals-and-the-fbi-knows-it-yjnwfdw1p) · XDA Developers · 0 upvotes · 0 comments - [CVE-2026-0826: How an Old Bug Can Feed AI-Powered Impersonation](https://daily.dev/posts/cve-2026-0826-how-an-old-bug-can-feed-ai-powered-impersonation-lqgyapfvo) · Rapid7 Cybersecurity Blog · 0 upvotes · 0 comments --- Tags: [#security](https://daily.dev/tags/security), [#cisco](https://daily.dev/tags/cisco) [View this post on daily.dev](https://daily.dev/posts/nobody-uses-this-old-stuff--wr4rhb4on) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Nobody Uses This Old Stuff!","url":"https://daily.dev/posts/nobody-uses-this-old-stuff--wr4rhb4on","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/nobody-uses-this-old-stuff--wr4rhb4on"},"datePublished":"2026-08-13T18:08:49.468Z","dateModified":"2026-09-13T18:55:33.357Z","description":"A hotel's use of a 15-18 year old, end-of-life Cisco IP phone 7975 illustrates how legacy hardware persists in real-world environments.
