Descripción técnica

A flaw was found in dracut. The die() error-handling function writes its message into a shell script under the initramfs emergency-hook directory without properly shell-quoting it. When the message contains data derived from the DHCP ROOT_PATH option, an attacker on the adjacent network who controls a rogue DHCP server can inject a command-substitution sequence that executes as root the next time dracut sources its emergency hook scripts during standard boot-failure handling.

——0PHP_CodeSniffer tokenizes PHP files and detects violations of a defined set of coding standards. Prior to versions 3.13.6 and 4.0.2, PHP_CodeSniffer contains a command injection vulnerability in the code that generates the Gitblame, Hgblame, and Svnblame report formats. As a result, running PHP_CodeSniffer over untrusted files, for example in a continuous integration pipeline that scans pull requests, or on a developer machine reviewing third party code, could result in attacker controlled shell commands being executed when the Gitblame, Hgblame, or Svnblame report processes a file whose name contains shell metacharacters. Users using the default Full report, or any of the other non-blame reports, are not affected. Users on a runtime platform which does not allow filenames to contain shell metacharacters, such as " and ;, are not affected. This issue is fixed in versions 3.13.6 and 4.0.2.17h CVE-2026-637257.2 ALT

——0sysPass's FileBackupService::doBackupFiles() in lib/SP/Services/Backup/FileBackupService.php around line 388 builds a tar shell command by string-concatenating the backup directory path $this->path directly into the command line ('tar czf ' . $backupFileApp . ' ' . BASE_PATH . ' --exclude \"' . $this->path . '\" 2>&1') and passes the result to PHP's exec() with no application of escapeshellarg() and no validation of the path against a safe character set. The $this->path value is read from the sysPass configuration, which is persisted in the database and writable through the admin settings API and the admin UI. An administrator (or an attacker who has obtained an admin API token or admin session) can therefore store a backup path containing shell metacharacters and trigger a backup operation to execute arbitrary OS commands as the web server process user (typically www-data or apache). Because sysPass is a password manager whose sole purpose is to hold credentials for other systems, code execution as the web-server user permits reading sysPass's master password and encryption key from memory or configuration files, decrypting every stored credential in the database, exporting the entire password vault, pivoting to internal systems using the disclosed credentials, and installing persistent backdoors on the password-manager host.17h CVE-2026-672619.8 CRÍ

——0Dell Virtual Storage Integrator for VMware vSphere Client, versions prior to 10.11.1.0, contain(s) an OS Command Injection vulnerability in the IAPI component. A remote unauthenticated attacker could potentially exploit this vulnerability, leading to the execution of arbitrary OS commands on the application's underlying operating system with root privileges. Exploitation may lead to a complete system takeover by an attacker. This vulnerability is considered critical as it allows an unauthenticated remote attacker to achieve arbitrary code execution as root, potentially compromising the entire VSI deployment and underlying infrastructure. Dell recommends customers to upgrade at the earliest opportunity.17h CVE-2026-539759.8 CRÍ

——0OpenChamber 1.11.7 contains an unauthenticated remote code execution vulnerability that allows remote attackers to execute arbitrary shell commands by sending crafted POST requests to the /api/fs/exec endpoint, which passes commands verbatim to Node.js spawn() without any allowlist, blocklist, or argument validation. The authentication middleware becomes a no-op when UI_PASSWORD is not configured, matching the default Docker deployment, enabling attackers to execute arbitrary OS commands as the application user and retrieve full command output including stdout, stderr, and exit code from the server response.23h CVE-2026-190367.2 ALT
