CVE-2021-3450 10 Fedoraproject, Freebsd, Mcafee and 7 more 35 Fedora, Freebsd, Web Gateway and 32 more 2024-02-28 5.8 MEDIUM 7.4 HIGH
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 encoded elliptic curve parameters was added as an additional strict check. An error in the implementation of this check meant that the result of a previous check to confirm that certificates in the chain are valid CA certificates was overwritten. This effectively bypasses the check that non-CA certificates must not be able to issue other certificates. If a "purpose" has been configured then there is a subsequent opportunity for checks that the certificate is a valid CA. All of the named "purpose" values implemented in libcrypto perform this check. Therefore, where a purpose is set the certificate chain will still be rejected even when the strict flag has been used. A purpose is set by default in libssl client and server certificate verification routines, but it can be overridden or removed by an application. In order to be affected, an application must explicitly set the X509_V_FLAG_X509_STRICT verification flag and either not set a purpose for the certificate verification or, in the case of TLS client or server applications, override the default purpose. OpenSSL versions 1.1.1h and newer are affected by this issue. Users of these versions should upgrade to OpenSSL 1.1.1k. OpenSSL 1.0.2 is not impacted by this issue. Fixed in OpenSSL 1.1.1k (Affected 1.1.1h-1.1.1j).
CVE-2020-5793 2 Microsoft, Tenable 3 Windows, Nessus, Nessus Agent 2024-02-28 7.2 HIGH 7.8 HIGH
A vulnerability in Nessus versions 8.9.0 through 8.12.0 for Windows & Nessus Agent 8.0.0 and 8.1.0 for Windows could allow an authenticated local attacker to copy user-supplied files to a specially constructed path in a specifically named user directory. An attacker could exploit this vulnerability by creating a malicious file and copying the file to a system directory. The attacker needs valid credentials on the Windows system to exploit this vulnerability.
CVE-2020-5765 1 Tenable 1 Nessus 2024-02-28 3.5 LOW 5.4 MEDIUM
Nessus 8.10.0 and earlier were found to contain a Stored XSS vulnerability due to improper validation of input during scan configuration. An authenticated, remote attacker could potentially exploit this vulnerability to execute arbitrary code in a user's session. Tenable has implemented additional input validation mechanisms to correct this issue in Nessus 8.11.0.
CVE-2020-5774 1 Tenable 1 Nessus 2024-02-28 3.6 LOW 7.1 HIGH
Nessus versions 8.11.0 and earlier were found to maintain sessions longer than the permitted period in certain scenarios. The lack of proper session expiration could allow attackers with local access to login into an existing browser session.
CVE-2016-1000028 1 Tenable 1 Nessus 2024-02-28 3.5 LOW 4.8 MEDIUM
Tenable Nessus before 6.8 has a stored XSS issue that requires admin-level authentication to the Nessus UI, and would only potentially impact other admins. (Tenable ID 5198).
CVE-2019-3982 1 Tenable 1 Nessus 2024-02-28 4.0 MEDIUM 6.5 MEDIUM
Nessus versions 8.6.0 and earlier were found to contain a Denial of Service vulnerability due to improper validation of specific imported scan types. An authenticated, remote attacker could potentially exploit this vulnerability to cause a Nessus scanner to become temporarily unresponsive.
CVE-2016-1000029 1 Tenable 1 Nessus 2024-02-28 3.5 LOW 4.8 MEDIUM
Tenable Nessus before 6.8 has a stored XSS issue that requires admin-level authentication to the Nessus UI, and would potentially impact other admins (Tenable IDs 5218 and 5269).
CVE-2018-20843 7 Canonical, Debian, Fedoraproject and 4 more 9 Ubuntu Linux, Debian Linux, Fedora and 6 more 2024-02-28 7.8 HIGH 7.5 HIGH
In libexpat in Expat before 2.2.7, XML input including XML names that contain a large number of colons could make the XML parser consume a high amount of RAM and CPU resources while processing (enough to be usable for denial-of-service attacks).
CVE-2019-3974 2 Microsoft, Tenable 2 Windows, Nessus 2024-02-28 8.5 HIGH 8.1 HIGH
Nessus 8.5.2 and earlier on Windows platforms were found to contain an issue where certain system files could be overwritten arbitrarily, potentially creating a denial of service condition.
CVE-2019-3962 1 Tenable 1 Nessus 2024-02-28 4.3 MEDIUM 3.3 LOW
Content Injection vulnerability in Tenable Nessus prior to 8.5.0 may allow an authenticated, local attacker to exploit this vulnerability by convincing another targeted Nessus user to view a malicious URL and use Nessus to send fraudulent messages. Successful exploitation could allow the authenticated adversary to inject arbitrary text into the feed status, which will remain saved post session expiration.
CVE-2019-3961 1 Tenable 1 Nessus 2024-02-28 4.3 MEDIUM 6.1 MEDIUM
Nessus versions 8.4.0 and earlier were found to contain a reflected XSS vulnerability due to improper validation of user-supplied input. An unauthenticated, remote attacker could potentially exploit this vulnerability via a specially crafted request to execute arbitrary script code in a users browser session.
CVE-2019-3923 1 Tenable 1 Nessus 2024-02-28 3.5 LOW 5.4 MEDIUM
Nessus versions 8.2.1 and earlier were found to contain a stored XSS vulnerability due to improper validation of user-supplied input. An authenticated, remote attacker could potentially exploit this vulnerability via a specially crafted request to execute arbitrary script code in a user's browser session. Tenable has released Nessus 8.2.2 to address this issue.
CVE-2018-5407 7 Canonical, Debian, Nodejs and 4 more 20 Ubuntu Linux, Debian Linux, Node.js and 17 more 2024-02-28 1.9 LOW 4.7 MEDIUM
Simultaneous Multi-threading (SMT) in processors can enable local users to exploit software vulnerable to timing attacks via a side-channel timing attack on 'port contention'.
CVE-2019-1559 13 Canonical, Debian, F5 and 10 more 90 Ubuntu Linux, Debian Linux, Big-ip Access Policy Manager and 87 more 2024-02-28 4.3 MEDIUM 5.9 MEDIUM
If an application encounters a fatal protocol error and then calls SSL_shutdown() twice (once to send a close_notify, and once to receive one) then OpenSSL can respond differently to the calling application if a 0 byte record is received with invalid padding compared to if a 0 byte record is received with an invalid MAC. If the application then behaves differently based on that in a way that is detectable to the remote peer, then this amounts to a padding oracle that could be used to decrypt data. In order for this to be exploitable "non-stitched" ciphersuites must be in use. Stitched ciphersuites are optimised implementations of certain commonly used ciphersuites. Also the application must call SSL_shutdown() twice even if a protocol error has occurred (applications should not do this but some do anyway). Fixed in OpenSSL 1.0.2r (Affected 1.0.2-1.0.2q).
CVE-2018-1141 1 Tenable 1 Nessus 2024-02-28 4.4 MEDIUM 7.0 HIGH
When installing Nessus to a directory outside of the default location, Nessus versions prior to 7.0.3 did not enforce secure permissions for sub-directories. This could allow for local privilege escalation if users had not secured the directories in the installation location.
