Tenable ≫ Nessus Network Monitor

A stored cross site scripting vulnerability exists in Nessus Network Monitor where an authenticated, privileged local attacker could inject arbitrary code into the NNM UI via the local CLI.

Under certain conditions, Nessus Network Monitor could allow a low privileged user to escalate privileges to NT AUTHORITY\SYSTEM on Windows hosts by replacing a specially crafted file.

NNM failed to properly set ACLs on its installation directory, which could allow a low privileged user to run arbitrary code with SYSTEM privileges where NNM is installed to a non-standard location

Under certain conditions, Nessus Network Monitor was found to not properly enforce input validation. This could allow an admin user to alter parameters that could potentially allow a blindSQL injection.

In order to decrypt SM2 encrypted data an application is expected to call the API function EVP_PKEY_decrypt(). Typically an application will call this function twice. The first time, on entry, the "out" parameter can be NULL and, on exit, the "outlen...

ASN.1 strings are represented internally within OpenSSL as an ASN1_STRING structure which contains a buffer holding the string data and a field holding the buffer length. This contrasts with normal C strings which are repesented as a buffer for the s...

An OpenSSL TLS server may crash if sent a maliciously crafted renegotiation ClientHello message from a client. If a TLSv1.2 renegotiation ClientHello omits the signature_algorithms extension (where it was present in the initial ClientHello), but incl...

The X509_V_FLAG_X509_STRICT flag enables additional security checks of the certificates present in a certificate chain. It is not set by default. Starting from OpenSSL version 1.1.1h a check to disallow certificates in the chain that have explicitly ...

Calls to EVP_CipherUpdate, EVP_EncryptUpdate and EVP_DecryptUpdate may overflow the output length argument in some cases where the input length is close to the maximum permissable length for an integer on the platform. In such cases the return value ...

The OpenSSL public API function X509_issuer_and_serial_hash() attempts to create a unique hash value based on the issuer and serial number data contained within an X509 certificate. However it fails to correctly handle any errors that may occur while...
