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...

bind: A logic error in code which checks TSIG validity can be used to trigger an assertion failure in tsig.c

An assertion failure was found in BIND, which checks the validity of messages containing TSIG resource records. This flaw allows an attacker that knows or successfully guesses the name of the TSIG key used by the server to use a specially-crafted message, potentially causing a BIND server to reac...

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...

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...

Nextcloud: Message Authentication Codes calculated by the Default Encryption Module allow an attacker to silently overwrite blocks in a file

First: The default encryption module bundled with the Nextcloud Server creates SHA256-HMAC based message authentication codes for each individual 6072 byte-sized block of data. These are the steps to calculate the MAC: Take the user password and harden it with SHA256-PBKDF2 denoted as $passPhrase...

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...
