CVE-2008-1198
HighSummary
Domyślny skrypt ifup IPSec w Red Hat Enterprise Linux od wersji 3 do 5 konfiguruje racoon do używania agresywnego trybu IKE zamiast głównego trybu IKE. Umożliwia to zdalnym atakującym przeprowadzanie ataków brute force poprzez podsłuchiwanie niezaszyfrowanego hasha klucza współdzielonego (PSK).
Risk Assessment
Organizacja jest narażona na ataki brute force, co może prowadzić do ujawnienia klucza współdzielonego i kompromitacji połączeń VPN. To zwiększa ryzyko nieautoryzowanego dostępu do zasobów sieciowych.
Recommendation
Zaleca się modyfikację skryptu ifup IPSec, aby używał głównego trybu IKE zamiast agresywnego, oraz wdrożenie dodatkowych środków zabezpieczających, takich jak silniejsze hasła i monitorowanie ruchu sieciowego.

Pandora contains a path traversal vulnerability in its archive extraction worker. When processing a specially crafted archive or disk image, attacker-controlled file paths could be used without ensuring that the resulting destination remained within the intended extraction directory. An attacker able to submit a malicious file for analysis could use path traversal sequences or crafted paths to cause extracted content to be written outside the designated extraction directory, potentially overwriting files accessible to the Pandora worker process.

An OS command injection weakness in the read-only enforcement of the SQL validation component in Amazon awslabs postgres-mcp-server before 1.1.7 might allow an unauthenticated actor to execute operating system commands on the host of a self-managed PostgreSQL server by placing a crafted COPY ... TO PROGRAM statement into content that is processed when an authenticated user interacts with the MCP server in its default read-only mode.
- CVE-2026-54694Critical
SkillTree before version 4.4.2 contains an XSS vulnerability resulting from a combination of two flaws: lack of HTML encoding in StringHighlighter.js and use of v-html in HighlightedValue.vue. An attacker can register an account with malicious firstName/lastName/nickname fields, and when an administrator opens the Quiz Runs page, the payload executes in their browser. There are three attack paths with escalating impact: basic XSS, remote script loading via import(), and CSRF token theft.
- CVE-2026-87929Critical
MaxSite CMS through 109.6 ships with a hardcoded session encryption key in application/config/config.php that is never changed during installation, allowing unauthenticated attackers to forge administrator session cookies. Attackers can mint a malicious ci_session cookie with administrator privileges by computing an HMAC-SHA1 using the publicly known encryption key, bypassing authentication checks in is_login() and mso_check_allow() functions.
- CVE-2026-47156Critical
MantisBT versions 2.28.3 and earlier contain a critical authentication bypass in the SOAP API's mci_check_login() function. Any user knowing any valid cookie_string can authenticate as any other user (knowing their username), including the administrator, without knowing the target's password. The vulnerability is exploitable with zero prior access on default installations because self-registration is enabled by default.

Cash Collect contains an improper authorization vulnerability in the Sage AR Automation API. Administrative functions do not properly verify user privileges, allowing authenticated low-privileged users to create administrator accounts and obtain elevated privileges.
- CVE-2026-67403Critical
Cash Collect contains an improper authorization vulnerability in the Sage AR Automation API. Insufficient tenant-level authorization checks allow authenticated users to access administrative resources belonging to other tenants by specifying a valid non predictable tenant identifier.

eprosima Fast DDS versions prior to 2.6.12, 2.14.6, 3.2.4, 3.3.1, and 3.4.2 have a remotely triggerable Out-of-Bounds Read while processing RTPS DATA_FRAG submessages. An attacker can craft a DATA_FRAG with a large sampleSize but a small actual payload, leading to reading past the received UDP datagram buffer and copying adjacent heap memory into the reassembly buffer.

A heap-based buffer overflow in VPN certificate ASN.1 decoding may allow an unauthenticated remote attacker to execute arbitrary code on Check Point Quantum Security Management and Quantum Security Gateway systems.
Original NVD description (English source)
The default IPSec ifup script in Red Hat Enterprise Linux 3 through 5 configures racoon to use aggressive IKE mode instead of main IKE mode, which makes it easier for remote attackers to conduct brute force attacks by sniffing an unencrypted preshared key (PSK) hash.
