CVE-2020-15099 Exposure of Sensitive Information to an Unauthorized Actor in TYPO3 CMS

In TYPO3 CMS greater than or equal to 9.0.0 and less than 9.5.20, and greater than or equal to 10.0.0 and less than 10.4.6, in a case where an attacker manages to generate a valid cryptographic message authentication code HMAC-SHA1 - either by using a different existing vulnerability or in case t...

Sensitive Information Disclosure in extension "Media Content Element" (mediace)

It has been discovered that an internal verification mechanism can be used to generate arbitrary checksums. This allows to inject arbitrary data having a valid cryptographic message authentication code HMAC-SHA1 and can lead to various attack chains as described below...

Potential Privilege Escalation

In case an attacker manages to generate a valid cryptographic message authentication code HMAC-SHA1 - either by using a different existing vulnerability or in case the internal encryptionKey was exposed - it is possible to retrieve arbitrary files of a TYPO3 installation. This includes the...

Critical vulnerability in legacy versions of TYPO3 CMS

It has been discovered that an internal verification mechanism can be used to generate arbitrary checksums. This allows to inject arbitrary data having a valid cryptographic message authentication code HMAC-SHA1 and can lead to various attack chains as described below...

CVE-2019-19092

ABB eSOMS versions 4.0 to 6.0.3 use ASP.NET Viewstate without Message Authentication Code MAC. Alterations to Viewstate might thus not be noticed...

CVE-2019-19092

CVE-2019-19092 affects ABB eSOMS versions 4.0 to 6.0.3, where the ASP.NET Viewstate is used without a MAC, allowing alterations to go unnoticed. The Red Hat, NVD, CVE lists consistently describe this external-state data issue; ENISA/EUVD entries also reference related ABB eSOMS risks. Public deta...

CVE-2019-19092 ABB eSOMS: Viewstate without MAC Signature

ABB eSOMS versions 4.0 to 6.0.3 use ASP.NET Viewstate without Message Authentication Code MAC. Alterations to Viewstate might thus not be noticed...

jenkins: Non-constant time HMAC comparison

Jenkins 2.218 and earlier, LTS 2.204.1 and earlier used a non-constant time comparison function when validating an HMAC...

openssl: 0-byte record padding oracle

If an application encounters a fatal protocol error and then calls SSLshutdown twice once to send a closenotify, 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...

EulerOS Virtualization 3.0.1.0 : ntp (EulerOS-SA-2019-1557)

According to the versions of the ntp packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities : - It was found that ntpd did not check whether a Message Authentication Code MAC was present in a received packet when ntpd was...

Insufficient Entropy In Key Generation Algorithm

The Network Time Protocol NTP is used to synchronize a computer's time with another referenced time source. It was found that because NTP's access control was based on a source IP address, an attacker could bypass source IP restrictions and send malicious control and configuration packets by...

A Go implementation of Poly1305 that makes sense

Poly1305 is a Message Authentication Code--a cryptographic primitive for authenticating a message with a shared secret key, like HMAC. Although its really a fraction of the complexity of e.g. elliptic curves, most of the implementations Ive read look decidedly like magic, mysteriously multiplying...

Sensitive Data Exposure

Overview All versions of rails-session-decoder are missing verification of the Message Authentication Code appended to the cookies. This may lead to decryption of cipher text thus exposing encrypted information. Recommendation No fix is currently available. Consider using an alternative module...

The vulnerability of the FortiOS operating system’s SSL-VPN implementation, caused by errors in processing input data, allows a hacker to replace encrypted traffic with malicious data.

The vulnerability of the SSL-VPN implementation in the FortiOS operating system arises due to errors in processing input data. Exploiting this vulnerability allows a malicious actor to replace encrypted traffic using a specially generated MAC...

Unverifiable Symmetric Encryption

spring-cloud-config has a flaw which allows malicious manipulation of symmetric encryptions. The vulnerability exists because its default symmetric encryption does not use a Message Authentication Code MAC to verify the authenticity of encrypted message...

CVE-2015-7848

An integer overflow can occur in NTP-dev.4.3.70 leading to an out-of-bounds memory copy operation when processing a specially crafted private mode packet. The crafted packet needs to have the correct message authentication code and a valid timestamp. When processed by the NTP daemon, it leads to ...
