2026-06-17 2026Rapid7 Analysis: CVE-2022-3786RCEAnalysis of CVE-2022-3786 details an arbitrary-length overflow vulnerability in OpenSSL's Punycode library within libcrypto.so. This flaw, occurring during Punycode domain name parsing via the `ossl_a2ulabel` function, allows for infinite period characters to be appended to a buffer, potentially leading to denial of service or, in rare circumstances, exploitable memory corruption. While exploitation is unlikely due to specific memory layout requirements, affected versions include OpenSSL 3.0.0 through 3.0.6. Updating to OpenSSL 3.0.7 is recommended.
2026-06-17 2026Rapid7 Analysis: CVE-2023-42793RCEAnalysis of CVE-2023-42793 reveals a critical authentication bypass in JetBrains TeamCity, affecting versions prior to 2023.05.4. This vulnerability, stemming from an improper handling of the wildcard path `/**/RPC2` within the `RequestInterceptors` class, allows unauthenticated attackers to achieve remote code execution. By exploiting this flaw, attackers can gain access to sensitive data like source code and build artifacts, potentially enabling supply chain attacks. The analysis details patch diffing using BeyondCompare and decompilation with cfr to identify the root cause in `RequestInterceptors.java` and the target endpoint within the `rest-api.jar`.
2026-06-17 2026Rapid7 Analysis: CVE-2023-46747RCEAnalysis of CVE-2023-46747 details an unauthenticated remote code execution vulnerability in F5 BIG-IP's Traffic Management User Interface (TMUI). This flaw, stemming from mishandled AJP requests between Apache and the AJP server, allows attackers to smuggle AJP requests. By crafting specific requests, an attacker can create a new administrator user, change its password, and then exploit the system to leak hashes or execute OS commands via the `mgmt/tm/util/bash` resource, achieving full device compromise.
2026-06-17 2026Rapid7 Analysis: CVE-2024-12356SQLiAnalysis of CVE-2024-12356, a critical unauthenticated RCE in BeyondTrust Privileged Remote Access and Remote Support, reveals it was exploited as a zero-day alongside a newly discovered PostgreSQL vulnerability, CVE-2025-1094. Rapid7's research indicates CVE-2024-12356, more accurately an argument injection (CWE-88) than command injection (CWE-77), often relies on CVE-2025-1094 for RCE. While the BeyondTrust patch addresses both vulnerabilities, Rapid7 also found a method to exploit CVE-2025-1094 independently in certain implementations.
2026-04-22 2026Grav CMS Twig SSTI Authenticated Sandbox Bypass RCESSTIModule for exploiting CVE-2025-66294, a Grav CMS Twig SSTI vulnerability that bypasses sandbox restrictions for remote code execution.
