Improper access control in Group Sharing prior to versions 13.0.6.15 in Android S(12), 13.0.6.14 in Android R(11) and below allows attackers to access device information. Improper access control vulnerability in Broadcaster in Group Sharing prior to versions 13.0.6.15 in Android S(12), 13.0.6.14 in Android R(11) and below allows attackers to identify the device. Jenkins Android Signing Plugin 2.2.5 and earlier does not perform a permission check in a method implementing form validation, allowing attackers with Item/Read permission but without Item/Workspace or Item/Configure permission to check whether attacker-specified file patterns match workspace contents.
#SOPHOS POWER AND DISK LED BLINK PASSWORD#
This hardcoded password is hashed but stored within the config.php file server-side as well as in clear-text on the android client device by default. There are no known workarounds for this issue.īilde2910 Hauk v1.6.1 requires a hardcoded password which by default is blank. It is recommended that the Nextcloud Android app is upgraded to 3.21.0. This may lead to a leak of sensitive information in some cases. As a result access to internal files of the from within the Nextcloud Android app is possible. Internal paths to the Nextcloud Android app files are not properly protected. Nextcloud android is the official Android client for the Nextcloud home server platform. As a workaroubnd, current users of the SDK can disable key forwarding in their forks using `CryptoService#enableKeyGossiping(enable: Boolean)`. Clients need to ensure that messages decrypted with a key with `trusted = false` are decorated appropriately (for example, by showing a warning for such messages). The SDK now sets a `trusted` flag on the decrypted message upon decryption, based on whether the key used to decrypt the message was received from a trusted source. The matrix-android-sdk2 will now only accept forwarded keys in response to previously issued requests and only from own, verified devices. Starting with version 1.5.1, the default policy for accepting key forwards has been made more strict in the matrix-android-sdk2. This attack is possible due to the key forwarding strategy implemented in the matrix-android-sdk2 that is too permissive. Such messages will be marked with a grey shield on some platforms, but this may be missing in others. Prior to version 1.5.1, an attacker cooperating with a malicious homeserver can construct messages appearing to have come from another person. Matrix-android-sdk2 is the Matrix SDK for Android. This attack requires coordination between a malicious home server and an attacker, so those who trust their home servers do not need a workaround. Out of caution, several other checks have been audited or added. matrix-android-sdk2 version 1.5.1 has been modified to only accept Olm-encrypted to-device messages and to stop signing backups on a successful decryption.
These attacks are possible due to a protocol confusion vulnerability that accepts to-device messages encrypted with Megolm instead of Olm.
matrix-android-sdk2 would then additionally sign such a key backup with its device key, spilling trust over to other devices trusting the matrix-android-sdk2 device. This can allow, for example, to inject the key backup secret during a self-verification, to make a targeted device start using a malicious key backup spoofed by the homeserver. Additionally, a sophisticated attacker cooperating with a malicious homeserver could employ this vulnerability to perform a targeted attack in order to send fake to-device messages appearing to originate from another user. Prior to version 1.5.1, an attacker cooperating with a malicious homeserver can construct messages that legitimately appear to have come from another person, without any indication such as a grey shield.
