CVE-2017-11131

An issue was discovered in heinekingmedia StashCat through 1.7.5 for Android, through 0.0.80w for Web, and through 0.0.86 for Desktop. For authentication, the user password is hashed directly with SHA-512 without a salt or another key-derivation mechanism to enable a secure secret for...

CVE-2017-11132

An issue was discovered in heinekingmedia StashCat before 1.5.18 for Android. No certificate pinning is implemented; therefore the attacker could issue a certificate for the backend and the application would not notice it...

CVE-2017-11129

An issue was discovered in heinekingmedia StashCat through 1.7.5 for Android. The keystore is locked with a hard-coded password. Therefore, everyone with access to the keystore can read the content out, for example the private key of the user...

CVE-2017-11130

An issue was discovered in heinekingmedia StashCat through 1.7.5 for Android, through 0.0.80w for Web, and through 0.0.86 for Desktop. The product's protocol only tries to ensure confidentiality. In the whole protocol, no integrity or authenticity checks are done. Therefore man-in-the-middle...

CVE-2017-11134

An issue was discovered in heinekingmedia StashCat through 1.7.5 for Android. The login credentials are written into a log file on the device. Hence, an attacker with access to the logs can read them...

Authorization

An issue was discovered in heinekingmedia StashCat through 1.7.5 for Android, through 0.0.80w for Web, and through 0.0.86 for Desktop. The logout mechanism does not check for authorization. Therefore, an attacker only needs to know the device ID. This causes a denial of service. This might be...
