Talos discloses multiple zero-day vulnerabilities, two of which could lead to code execution
Summary: Cisco Talos disclosed three zero-day vulnerabilities that were unpatched as of Wednesday, May 8, after vendors missed the 90-day patch or communication deadline. Two could lead to arbitrary code execution and carry CVSS scores of 9.8: a use-after-free in the Tinyproxy HTTP proxy daemon's Connection header (CVE-2023-49606), triggered by an unauthenticated HTTP request, and a heap-based buffer overflow in stb_vorbis.c (CVE-2023-47212), triggered by a crafted .ogg file; the third, in the Milesight UR32L router (CVE-2023-47166), lets an adversary push arbitrary firmware because the device never checks uploaded firmware validity.
Why it matters: Two of these flaws score 9.8 and one needs no authentication at all - a single unauthenticated HTTP request to a Tinyproxy instance can set off memory corruption that leads to remote code execution.
