All news with #insecure deserialization tag

🔒 Three vulnerabilities affecting the Sitecore Experience Platform can be chained to escalate from HTML cache poisoning to remote code execution. Researchers describe a pre-auth HTML cache reflection (CVE-2025-53693) combined with an insecure deserialization RCE (CVE-2025-53691) and an ItemService API information-disclosure bug (CVE-2025-53694) that permits cache key enumeration and poisoned HTML injection. Sitecore issued patches in June and July 2025; administrators should apply updates, restrict ItemService exposure to trusted networks, and consider WAF rules and other mitigations to reduce the chaining risk.

⚠️ Siemens and CISA published an advisory describing a deserialization of untrusted data flaw in multiple engineering and automation products that has been assigned CVE-2024-54678 and a CVSS v3.1 base score of 8.2. The vulnerability permits a local, authenticated attacker to misuse a Windows Named Pipe to cause type confusion and execute arbitrary code with application privileges. Siemens lists numerous affected SIMATIC, SIMOTION, SINAMICS, SIRIUS, and TIA Portal components and offers mitigations such as running affected software on single-user Windows hosts or restricting OS access to administrators; some products currently have no fix planned and are documented in SSA-693808.
