CVE-2023-29146
HighCVSS 8.2Exploitation Probability (EPSS)
Low risk2th percentile - higher than 2% of all known CVEs
Summary
In Malwarebytes EDR 1.0.11 on Linux, utility functions for calculating cryptographic hashes truncate data exceeding 4GB, causing an integer wrap-around. An attacker can create a hash collision for two different strings by appending 4GB of data to a shorter string.
Risk Assessment
An attacker could exploit this vulnerability to spoof data integrity, potentially bypassing threat detection mechanisms.
Recommendation
It is recommended to update Malwarebytes EDR to a version containing a fix for the data truncation issue.

SunEditor before 3.4.0 contains a stored cross-site scripting vulnerability because the html.clean() sanitizer's _normalizeURL() function decodes named entities like : to an empty string. Attackers can inject href values such as javascript: that pass the _isSafeURL() check but are decoded by browsers, executing JavaScript when victims click stored links.

OpenEMR from 7.0.1 before 8.4.0 contains a flaw in src/Common/Auth/OneTimeAuth.php that ignores the enforce_onetime_use and max_access_count flags, never revokes consumed service_auth tokens, and checks login_pin without rate limiting or strict comparison. Attackers holding a captured token can replay it or brute-force the PIN to open patient-portal sessions exposing PHI.
Original NVD description (English source)
The utility functions used by Malwarebytes EDR 1.0.11 on Linux for calculating a cryptographic hash of data bytes truncate the hashed data if it exceeds 4GB. This leads to an integer wrap-around if the data is larger than the maximum unsigned integer value (32-bit). Attackers could create a colliding hash value for two different strings by attaching 4GB of data to a string that is less than 4GB in size.
