Vulnerability in the PeopleSoft Enterprise PeopleTools product of Oracle PeopleSoft (component: Query). Supported versions that are affected are 8.59, 8.60 and 8.61. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise PeopleSoft Enterprise PeopleTools. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all PeopleSoft Enterprise PeopleTools accessible data as well as unauthorized access to critical data or complete access to all PeopleSoft Enterprise PeopleTools accessible data.

A flaw was found in nodejs. When too many connection attempts with an 'unknownProtocol' are established a leak of file descriptors can occur leading to a potential denial of service. If a file descriptor limit is configured on the system, then the server is unable to accept new connections and prevent the process also from opening. If no file descriptor limit is configured, then this can lead to an excessive memory usage and cause the system to run out of memory. The highest threat from this vulnerability is to system availability.

ckeditor is an open source WYSIWYG HTML editor with rich content support. A vulnerability has been discovered in the clipboard Widget plugin if used alongside the undo feature. The vulnerability allows a user to abuse undo functionality using malformed widget HTML, which could result in executing JavaScript code. It affects all users using the CKEditor 4 plugins listed above at version >= 4.13.0. The problem has been recognized and patched. The fix will be available in version 4.16.2.

A flaw was found in nodejs. A denial of service is possible when the whitelist includes “localhost6”. When “localhost6” is not present in /etc/hosts, it is just an ordinary domain that is resolved via DNS over the network. If the attacker controls the victim's DNS server or can spoof its responses, the DNS rebinding protection can be bypassed by using the “localhost6” domain. As long as the attacker uses the “localhost6” domain, they can still apply the attack described in CVE-2018-7160.

A flaw was found in Node.js, where it is vulnerable to a use-after-free attack. This flaw allows an attacker to exploit memory corruption to change process behavior. The highest threat from this vulnerability is to confidentiality and integrity.

Server or client applications that call the SSLcheckchain() function during or after a TLS 1.3 handshake may crash due to a NULL pointer dereference as a result of incorrect handling of the "signaturealgorithmscert" TLS extension. The crash occurs if an invalid or unrecognised signature algorithm is received from the peer. This could be exploited by a malicious peer in a Denial of Service attack. OpenSSL version 1.1.1d, 1.1.1e, and 1.1.1f are affected by this issue. This issue did not affect OpenSSL versions prior to 1.1.1d. Fixed in OpenSSL 1.1.1g (Affected 1.1.1d-1.1.1f).

CKEditor is vulnerable to a denial of service, caused by a regular expression denial of service (ReDoS) flaw in the dialog plugin. By sending a specially-crafted regex input, a remote attacker could exploit this vulnerability to cause a significant performance drop and results in a browser tab freeze.

OpenSSL could provide weaker than expected security, caused by a carry propagation flaw in the MIPS32 and MIPS64 squaring procedure. An attacker could exploit this vulnerability to launch further attacks on the system

Vulnerability in the PeopleSoft Enterprise PeopleTools product of Oracle PeopleSoft (component: SQR). Supported versions that are affected are 8.57, 8.58 and 8.59. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise PeopleSoft Enterprise PeopleTools. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all PeopleSoft Enterprise PeopleTools accessible data. CVSS 3.1 Base Score 6.5 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N).

Impact

Users who are using an HTTPS proxy to issue HTTPS requests and haven't configured their own SSLContext via proxyconfig. Only the default SSLContext is impacted.

Patches

urllib3 >=1.26.4 has the issue resolved. urllib3<1.26 is not impacted due to not supporting HTTPS requests via HTTPS proxies.

Workarounds

Upgrading is recommended as this is a minor release and not likely to break current usage.

Configuring an SSLContext with checkhostname=True and passing via proxyconfig instead of relying on the default SSLContext
