CVE Vulnerability Catalog

LibreNMS before version 26.8.0 contains an authentication bypass vulnerability in the REST API that allows unauthenticated attackers to access protected endpoints by sending numeric values instead of string tokens. Attackers can exploit MySQL type coercion by sending small integers like 0 through 9 to match token hashes, gaining access to API functionality including device credentials and administrative features that enable remote code execution through alert templates.

Affected versions of MISP contain insufficient validation of server-side outbound HTTP destinations in feed retrieval and TAXII discovery functionality. In feed processing, redirects were followed without validating the redirect scheme or destination, and original request headers were reused, potentially forwarding authentication headers or API credentials to a different host. Redirects could also target internal network resources, resulting in SSRF. The fix adds redirect validation, blocks internal destinations for cross-host redirects, strips configured feed credentials before following redirects to another host, and pins validated DNS results. The TAXII discovery endpoint had a related incomplete SSRF defense using gethostbyname() and comparing against only a few literal addresses, missing cases like IPv6 loopback (::1), numeric host encodings such as 0x7f000001, and multiple DNS records. The fix moves TAXII discovery to the shared URL egress validator.

Dell SCG 5.0 Appliance versions prior to 5.36.00.16 and Dell SCG 5.0 Application versions prior to 5.36.00.00 contain an Execution with Unnecessary Privileges vulnerability. An unauthenticated attacker with local access could potentially exploit this vulnerability, leading to Protection mechanism bypass. A low-privileged operator with SSH access to the SCG host can gain root-level access without a password by leveraging the exposed Docker socket. Additionally, an attacker who compromises a service within the orchestrator container can access the same socket and escape the container to obtain host-level control.

A flaw was found in FreeIPA. The self-managed OTP token ACI does not require authentication and does not restrict which attributes may be added alongside the token entry. An unauthenticated LDAP client can exploit this, combined with a related flaw in the underlying directory server's ACI evaluation (tracked separately), to create an arbitrary attacker-controlled Kerberos principal and have it added to the administrators group. This allows a remote, unauthenticated attacker to obtain genuine FreeIPA administrator-group membership and perform administrative operations against the directory and, on SID-enabled deployments, other IdM services.

A vulnerability in Bahçelievler Municipality BiHayat App allows authentication bypass due to improper restriction of excessive authentication attempts. This issue affects BiHayat App from version 2.1.7 before 2.3.

Dell SCG 5.0 Appliance versions prior to 5.36.00.16 and Dell SCG 5.0 Application versions prior to 5.36.00.00 contain a Missing Authorization vulnerability. An unauthenticated attacker with remote access could potentially exploit this vulnerability, leading to remote execution. The attacker can execute commands remotely on a target system by sending a specially crafted request to the application, bypassing intended restrictions on code execution.

A vulnerability was detected in Linksys RE7000 2.0.15. It affects the function platform_event_pingTest of the file /cgi-bin/json.cgi?PingTest in the PingTest Handler component. Manipulation of the arguments pingTestIp/pingTestPktSize/pingTestTimes results in OS command injection. The attack can be launched remotely. The exploit is now public and may be used.

A vulnerability was found in D-Link DIR-822A A_101 in the strcpy function of the file udhcpcd/serverpacket.c in the udhcpcd component. This manipulation causes a stack-based buffer overflow. The attack can be carried out remotely and the exploit is publicly disclosed.

A vulnerability was identified in Advantech WISE-6610 devices (multiple models) version 1.2.1_20251110 in the nodered_lib_apply function of the Node-RED Library component. Manipulation of the argument act leads to command injection. The attack can be launched remotely and the exploit is publicly available. The vendor released a fix in version 1.2.4_20260821.

A vulnerability was identified in Advantech WISE-6610 devices (multiple models) version 1.2.1_20251110 in the basicstation_apply function of the Basic Station Certificate-Deletion Handler component. Manipulation of the argument act causes command injection. The attack can be initiated remotely and the exploit is publicly disclosed. The vendor released a fix in version 1.2.4_20260821.

An authentication bypass vulnerability exists in the WebGUI of Series UNIVERGE IX-R/IX-V. A user could bypass authentication and execute arbitrary CLI commands by tampering with WebGUI messages and sending them to the device via internet.

A vulnerability in MojoX::Authentication for Perl before version 0.006 allows SAML authentication bypass because parse_assertion builds Net::SAML2::Binding::POST without a trust anchor. An attacker can sign a response with their own certificate and authenticate any NameID.

A vulnerability in Authen::SASL::Perl::DIGEST_MD5 for Perl before version 2.2100 allows acceptance of replayed authentication responses due to an unverified nonce in server_step. An attacker who observes a successful qop=auth exchange can replay the captured response in a later session and authenticate as that user without knowing the password.

A flaw in libcurl causes it to wrongly reuse an HTTP connection established for a given hostname using Negotiate authentication, when the initial request is made with empty credentials. This can cause user B's request to be sent over user A's previously authenticated connection.

A flaw in libcurl's handling of HTTP/2 Server Push streams, when the parent handle is set to share connections with other handles, can lead to use-after-free in the cleanup process.

A vulnerability was identified in Tenda HG10 (version 300001138) in the formgponConf function of the /boaform/admin/formgponConf file in the Boa component. Manipulation of the fmgpon_loid argument leads to OS command injection. The attack can be performed remotely, and the exploit is publicly available.

A vulnerability was found in Tenda HG10 (version 300001138) in the formURL function of the /boaform/admin/formURL file. Manipulation of the Keywd/urlFQDN arguments results in a buffer overflow. The attack can be initiated remotely, and the exploit has been made public.

The Frontend Admin by DynamiApps plugin for WordPress is vulnerable to Authentication Bypass to Account Takeover in all versions up to and including 3.29.12. The pre_update_value function lacks capability or ownership checks, and ActionPost::conditions_logic() short-circuits the current_user_can('edit_post') authorization gate when the post ID is non-numeric, allowing unauthenticated form submissions to be routed to arbitrary user records. This enables unauthenticated attackers to overwrite any user's email address, including an administrator's, and then use WordPress's native password-reset flow to take over the account.

The MemberDash plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to and including 1.8.5 via the 'id' parameter due to missing validation on a user-controlled key. This allows unauthenticated attackers to change the password of any WordPress user, including administrators, by supplying an arbitrary user ID during registration, and take over their account without any notification to the victim.
