Type: Data Breach
Title: None
Description: Client Bouygues depuis peu, j’imagine vu la taille de la fuite qu’il y a de grande chance que je sois concerné. Et j’avoue ne pas comprendre cette histoire de payer par IBAN de mémoire et j’en suis quasiment certain ma banque ne m’a jamais demandé de validé de mandat SEPA à la souscription. Si le risque de confirmer dès versements sans faire attention semble faible, voir plusieurs personne souscrire a des abonnement via mon IBAN me semble déjà plus probable. J’appellerai ma banque pour savoir mais s’il existe vraiment des entreprises capable de se faire valider automatiquement des mandat SEPA par les banques, alors il est clair que l’IBAN est l’une des pire faille de sécurité jamais faite, et ce par pure incompétence du système bancaire qui en plus viens se défausser sur vous pour que vous fassiez vous même la veille sur vos comptes pour signaler les virement frauduleux. Je ne vois pas comment on peut encore autorisé un processus pareil.

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to 7.1.2-9 and 6.9.13-34, there is a vulnerability in ImageMagick’s Magick++ layer that manifests when Options::fontFamily is invoked with an empty string. Clearing a font family calls RelinquishMagickMemory on _drawInfo->font, freeing the font string but leaving _drawInfo->font pointing to freed memory while _drawInfo->family is set to that (now-invalid) pointer. Any later cleanup or reuse of _drawInfo->font re-frees or dereferences dangling memory. DestroyDrawInfo and other setters (Options::font, Image::font) assume _drawInfo->font remains valid, so destruction or subsequent updates trigger crashes or heap corruption. This vulnerability is fixed in 7.1.2-9 and 6.9.13-34.
FeehiCMS version 2.1.1 has a Remote Code Execution via Unrestricted File Upload in Ad Management. FeehiCMS version 2.1.1 allows authenticated remote attackers to upload files that the server later executes (or stores in an executable location) without sufficient validation, sanitization, or execution restrictions. An authenticated remote attacker can upload a crafted PHP file and cause the application or web server to execute it, resulting in remote code execution (RCE).
PHPGurukul Billing System 1.0 is vulnerable to SQL Injection in the admin/index.php endpoint. Specifically, the username parameter accepts unvalidated user input, which is then concatenated directly into a backend SQL query.
NMIS/BioDose software V22.02 and previous versions contain executable binaries with plain text hard-coded passwords. These hard-coded passwords could allow unauthorized access to both the application and database.
NMIS/BioDose V22.02 and previous versions' installation directory paths by default have insecure file permissions, which in certain deployment scenarios can enable users on client workstations to modify the program executables and libraries.
