CVE-2026-15469

🔑 CVE-2026-15469 Hard-coded Mesh Group Private Key — TP-Link Deco XE75 / XE5300 / WE10800 A shared RSA-512 mesh group private key is baked into the firmware, letting a LAN-adjacent attacker impersonate a trusted mesh node, overwrite configuration, flash unsigned firmware, and pivot across the...

CVE-2026-15469

The use of hard-coded cryptographic key vulnerability has been identified in the mesh functionality of Deco XE75 v3, XE5300 v3.6 and WE10800 v3.6. A shared RSA-512 mesh group private key is present in the affected firmware and is used by the mesh protocol for node authentication. An attacker who...

CVE-2026-15469

A hard-coded shared RSA-512 mesh group private key is embedded in the firmware of TP-Link Deco XE75 v3, XE5300 v3.6, and WE10800 v3.6. The key is used by the mesh protocol for node authentication, meaning it is identical across all affected devices rather than being device-specific. An attacker w...

Internet Bug Bounty: CVE-2019-1551: rsaz_512_sqr overflow bug on x86_64

The CVE-2019-1551 vulnerability was an overflow bug in the x6464 Montgomery squaring procedure used in exponentiation with 512-bit moduli in the OpenSSL library. The vulnerability was found and reported by researchers. The issue was mitigated in the 1.1.1 and 1.0.2 versions of OpenSSL...

Breaking the Zeppelin Ransomware Encryption Scheme

Brian Krebs writes about how the Zeppelin ransomware encryption scheme was broken: The researchers said their break came when they understood that while Zeppelin used three different types of encryption keys to encrypt files, they could undo the whole scheme by factoring or computing just one of...
