A improper neutralization of special elements used in an sql command ('sql injection') vulnerability in Fortinet FortiDDoS-F 7.2.1 through 7.2.2 may allow attacker to execute unauthorized code or commands via sending crafted HTTP requests

CVE-2025-26466A flaw was found in the OpenSSH package. For each ping packet the SSH server receives, a pong packet is allocated in a memory buffer and stored in a queue of packages. It is only freed when the server/client key exchange has finished. A malicious client may keep sending such packages, leading to an uncontrolled increase in memory consumption on the server side. Consequently, the server may become unavailable, resulting in a denial of service attack.

A externally controlled reference to a resource in another sphere vulnerability in Fortinet allows attacker to poison web caches via crafted HTTP requests, where the Host header points to an arbitrary webserver

CVE-2024-6387 A signal handler race condition was found in OpenSSH's server (sshd), where a client does not authenticate within LoginGraceTime seconds (120 by default, 600 in old OpenSSH versions), then sshd's SIGALRM handler is called asynchronously. However, this signal handler calls various functions that are not async-signal-safe, for example, syslog(). This could lead to remote code execution with root privileges.

A improper neutralization of special elements used in an os command ('os command injection') in Fortinet FortiDDoS version 5.5.0 through 5.5.1, 5.4.2 through 5.4.0, 5.3.0 through 5.3.1, 5.2.0, 5.1.0, 5.0.0, 4.7.0, 4.6.0 and 4.5.0 and FortiDDoS-F version 6.3.0 through 6.3.1, 6.2.0 through 6.2.2, 6.1.0 through 6.1.4 allows an authenticated attacker to execute shell code as root via execute CLI commands.

A security regression (CVE-2006-5051) was discovered in OpenSSH's server (sshd). There is a race condition which can lead sshd to handle some signals in an unsafe manner. An unauthenticated, remote attacker may be able to trigger it by failing to authenticate within a set time period.

A permissive cross-domain policy with untrusted domains vulnerability in Fortinet FortiADC 7.1.0 - 7.1.1, FortiDDoS-F 6.3.0 - 6.3.4 and 6.4.0 - 6.4.1 allow an unauthorized attacker to carry out privileged actions and retrieve sensitive information via crafted web requests.

Multiple buffer copy without checking size of input ('classic buffer overflow') vulnerabilities [CWE-120] in FortiADC version 7.2.0 and before 7.1.2 & FortiDDoS-F version 6.5.0 and before 6.4.1 allows a privileged attacker to execute arbitrary code or commands via specifically crafted CLI requests.

An improper neutralization of special elements used in an OS command vulnerability [CWE-78] in FortiADC 5.x all versions, 6.0 all versions, 6.1 all versions, 6.2.0 through 6.2.4, 7.0.0 through 7.0.3, 7.1.0; FortiDDoS 4.x all versions, 5.0 all versions, 5.1 all versions, 5.2 all versions, 5.3 all versions, 5.4 all versions, 5.5 all versions, 5.6 all versions and FortiDDoS-F 6.4.0, 6.3.0 through 6.3.3, 6.2.0 through 6.2.2, 6.1.0 through 6.1.4 may allow an authenticated attacker to execute unauthorized commands via specifically crafted arguments to existing commands.

A use of hard-coded cryptographic key vulnerability [CWE-321] in FortiDDoS API 5.5.0 through 5.5.1, 5.4.0 through 5.4.2, 5.3.0 through 5.3.1, 5.2.0, 5.1.0 may allow an attacker who managed to retrieve the key from one device to sign JWT tokens for any device.

A buffer overflow [CWE-121] in the TFTP client library of FortiOS, may allow an authenticated local attacker to achieve arbitrary code execution via specially crafted command line arguments.

A buffer overflow [CWE-121] in the TFTP client library of FortiOS before 6.4.7 and FortiOS 7.0.0 through 7.0.2, may allow an authenticated local attacker to achieve arbitrary code execution via specially crafted command line arguments.

An exposure of sensitive system information to an unauthorized control sphere vulnerability [CWE-497] in FortiDDoS version 5.4.0, version 5.3.2 and below, version 5.2.0, version 5.1.0, version 5.0.0, version 4.7.0, version 4.6.0, version 4.5.0, version 4.4.2 and below, FortiDDoS-CM version 5.3.0, version 5.2.0, version 5.1.0, version 5.0.0, version 4.7.0, FortiVoice version 6.0.6 and below, FortiRecorder version 6.0.3 and below and FortiMail version 6.4.1 and below, version 6.2.4 and below, version 6.0.9 and below may allow a remote, unauthenticated attacker to obtain potentially sensitive software-version information by reading a JavaScript file.
