CAPEC-67DetailedDraft
String Format Overflow in syslog()
This attack targets applications and software that uses the syslog() function insecurely. If an application does not explicitely use a format string parameter in a call to syslog(), user input can be placed in the format string parameter leading to a format string injection attack. Adversaries can then inject malicious format string commands into the function call leading to a buffer overflow. There are many reported software vulnerabilities with the root cause being a misuse of the syslog() function.

CWE-20
The product receives input or data, but it does.
CWE-74
The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is pars
CWE-120
The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer.
CWE-134
The product uses a function that accepts a format string as an argument, but the format string originates from an external source.
CWE-680
The product performs a calculation to determine how much memory to allocate, but an integer overflow can occur that causes less memory to be allocated than expected, leading to a buffer overflow.
CWE-697
The product compares two entities in a security-relevant context, but the comparison is incorrect.

CVE-2026-25586SandboxJS is a JavaScript sandboxing library. Prior to 0.8.29, a sandbox escape is possible by shadowing hasOwnProperty on a sandbox object, which disables prototype whitelist enforcement in the property-access path. This permits direct access to __proto__ and other blocked prototype properties, enabling host Object.prototype pollution and persistent cross-sandbox impact. This vulnerability is fixed in 0.8.29.
CVE-2026-25520SandboxJS is a JavaScript sandboxing library. Prior to 0.8.29, The return values of functions aren't wrapped. Object.values/Object.entries can be used to get an Array containing the host's Function constructor, by using Array.prototype.at you can obtain the hosts Function constructor, which can be used to execute arbitrary code outside of the sandbox. This vulnerability is fixed in 0.8.29.

CVE-2026-21858n8n is an open source workflow automation platform. Versions starting with 1.65.0 and below 1.121.0 enable an attacker to access files on the underlying server through execution of certain form-based workflows. A vulnerable workflow could grant access to an unauthenticated remote attacker, resulting in exposure of sensitive information stored on the system and may enable further compromise depending on deployment configuration and workflow usage. This issue is fixed in version 1.121.0.
CVE-2026-0848NLTK versions <=3.9.2 are vulnerable to arbitrary code execution due to improper input validation in the StanfordSegmenter module. The module dynamically loads external Java .jar files without verification or sandboxing. An attacker can supply or replace the JAR file, enabling the execution of arbitrary Java bytecode at import time. This vulnerability can be exploited through methods such as model poisoning, MITM attacks, or dependency poisoning, leading to remote code execution. The issue arises from the direct execution of the JAR file via subprocess with unvalidated classpath input, allowing malicious classes to execute when loaded by the JVM.
CVE-2025-9962A buffer overflow vulnerability in Novakon P series allows attackers to gain root permission without prior authentication.This issue affects P series: P – V2001.A.C518o2.
CVE-2025-34300A template injection vulnerability exists in Sawtooth Software’s Lighthouse Studio versions prior to 9.16.14 via the ciwweb.pl http://ciwweb.pl/ Perl web application. Exploitation allows an unauthenticated attacker can execute arbitrary commands.
CVE-2025-34105A stack-based buffer overflow vulnerability exists in the built-in web interface of DiskBoss Enterprise versions 7.4.28, 7.5.12, and 8.2.14. The vulnerability arises from improper bounds checking on the path component of HTTP GET requests. By sending a specially crafted long URI, a remote unauthenticated attacker can trigger a buffer overflow, potentially leading to arbitrary code execution with SYSTEM privileges on vulnerable Windows hosts.
CVE-2025-34060A PHP objection injection vulnerability exists in the Monero Project’s Laravel-based forum software due to unsafe handling of untrusted input in the /get/image/ endpoint. The application passes a user-supplied link parameter directly to file_get_contents() without validation. MIME type checks using PHP’s finfo can be bypassed via crafted stream filter chains that prepend spoofed headers, allowing access to internal Laravel configuration files. An attacker can extract the APP_KEY from config/app.php, forge encrypted cookies, and trigger unsafe unserialize() calls, leading to reliable remote code execution.
CVE-2025-34043A remote command injection vulnerability exists in Vacron Network Video Recorder (NVR) devices v1.4 due to improper input sanitization in the board.cgi script. The vulnerability allows unauthenticated attackers to pass arbitrary commands to the underlying operating system via crafted HTTP requests. These commands are executed with the privileges of the web server process, enabling remote code execution and potential full device compromise. Exploitation evidence was observed by the Shadowserver Foundation on 2025-02-06 UTC.
