Low risk32th percentile - higher than 32% of all known CVEs
Summary
Podatność w protokole Simple Network Management Protocol (SNMP) w oprogramowaniu Cisco IOS XE może pozwolić uwierzytelnionemu, zdalnemu atakującemu na spowodowanie warunków odmowy usługi (DoS) na dotkniętym urządzeniu. Problem wynika z niewłaściwego zarządzania błędami podczas analizy określonego żądania SNMP.
Risk Assessment
Atakujący może wykorzystać tę podatność, wysyłając odpowiednie żądanie SNMP, co może prowadzić do nieoczekiwanego ponownego uruchomienia urządzenia i w rezultacie do stanu DoS. Dotyczy to wersji SNMP 1, 2c i 3.
Recommendation
Zaleca się monitorowanie i ograniczenie dostępu do SNMP, a także aktualizację oprogramowania Cisco IOS XE do najnowszej wersji, aby zminimalizować ryzyko związane z tą podatnością.

Postiz generates security-sensitive credentials using Math.random() instead of a cryptographically secure source. The same helper is used for OAuth access tokens, authorization codes, client secrets, organization API keys, and PKCE verifiers, meaning these credentials depend entirely on V8's deterministic xorshift128+ PRNG state. An unauthenticated OAuth dynamic client registration endpoint exposes freshly generated client credentials, giving attackers enough consecutive PRNG output to reconstruct that internal state and derive past and future values.

Dokploy is a free, self-hostable Platform as a Service (PaaS). Prior to 0.29.13, Dokploy organization members without Git provider access can retrieve plaintext provider credentials through github.one, gitlab.one, gitea.one, and bitbucket.one because those protected procedures return full provider rows without applying getAccessibleGitProviderIds or an organization check. The application.one route also returns nested GitHub, GitLab, Gitea, and Bitbucket relations from findApplicationById with GitHub App private keys, OAuth tokens, client secrets, webhook secrets, and app passwords even when hasGitProviderAccess is false.

LightRAG provides simple and fast retrieval-augmented generation. Prior to 1.5.5, the POST /login endpoint in lightrag/api/lightrag_server.py does not impose a rate limit, account lockout, delay, or counter for failed authentication attempts. A network attacker can submit password guesses at full request speed until a valid account password is found.

Lantronix SLC8000 before firmware v9.7.0.5, EMG8500/EMG7500 before firmware v9.7.0.1, and all firmware versions of SLB882/SLCx-03/SLCx-02 contain a path traversal vulnerability in the web management portal upload endpoint that allows authenticated attackers to write arbitrary data to any location on the device's filesystem, leading to remote code execution. The upload filename validation strips backslash characters but does not subsequently check for forward slashes when a backslash is detected; by supplying a filename containing both characters an attacker writes outside the intended upload directory to any writable path.

Lantronix SLC8000 before firmware v9.7.0.5, EMG8500/EMG7500 before firmware v9.7.0.1, and all firmware versions of SLB882/SLCx-03/SLCx-02 contain an authentication bypass vulnerability in the web management portal upload endpoint that allows unauthenticated attackers to read sensitive configuration files and upload files to arbitrary filesystem locations, leading to remote code execution. The web configuration server constructs the session cookie file path using snprintf with a fixed-size buffer; by supplying a cookie value of a specific length an attacker causes the path to truncate at the required delimiter and leverages path traversal to redirect authentication validation to an arbitrary on-disk file such as the local user database, bypassing all session checks.
- CVE-2026-80154Critical
All firmware versions of Lantronix SLC8000, EMG8500, EMG7500, SLB882, SLCx-03, and SLCx-02 contain an authentication bypass vulnerability in the web management portal that allows unauthenticated attackers to derive valid session tokens of logged-in users and bypass source IP and User-Agent validation. Session tokens are generated deterministically from the device model and the current time at one-second resolution, resulting in a small enumerable set of possible active tokens. Attackers can construct a crafted URI that exploits file extension handling in the web server path routing to bypass per-session source-address validation, then use a derived token from a different source address to gain elevated privileges.

Original NVD description (English source)
A vulnerability in the Simple Network Management Protocol (SNMP) subsystem of Cisco IOS XE Software could allow an authenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to improper error handling when parsing a specific SNMP request. An attacker could exploit this vulnerability by sending a specific SNMP request to an affected device. A successful exploit could allow the attacker to cause the device to reload unexpectedly, resulting in a DoS condition. This vulnerability affects SNMP versions 1, 2c, and 3. To exploit this vulnerability through SNMPv2c or earlier, the attacker must know a valid read-write or read-only SNMP community string for the affected system. To exploit this vulnerability through SNMPv3, the attacker must have valid SNMP user credentials for the affected system.
