A vulnerability was found in Bharti Airtel Xstream Fiber up to 20250123. It has been rated as problematic. This issue affects some unknown processing of the component WiFi Password Handler. The manipulation leads to use of weak credentials. The attack needs to be done within the local network. The complexity of an attack is rather high. The exploitation is known to be difficult. The exploit has been disclosed to the public and may be used. It is recommended to change the configuration settings. The vendor was contacted early about this disclosure but did not respond in any way.Show less

After gaining access to the firmware of a charging station, a file at <redacted> can be accessed to obtain default credentials that are the same across all Iocharger AC model EV chargers. This issue affects Iocharger firmware for AC models before firmware version 25010801. The issue is addressed by requiring a mandatory password change on first login, it is still recommended to change the password on older models. Likelihood: Moderate – The attacker will first have to abuse a code execution or file inclusion vulnerability (for example by using <redacted>.sh) to gain access to the <redacted>.json file, or obtain a firmware dump of the charging station or obtain the firmware via other channels. Impact: Critical – All chargers using Iocharger firmware for AC models started with the same initial password. For models with firmware version before 25010801 a password change was not mandatory. It is therefore very likely that this firmware password is still active on many chargers. These credentials could, once obtained, allow an attacker to log into many Iocharger charging station, and allow them to execute arbitrary commands via the System → Custom page. CVSS clarification: Any network interface serving the web ui is vulnerable (AV:N) and there are not additional security measures to circumvent (AC:L), nor does the attack require and existing preconditions (AT:N). The attack is authenticated, and requires high privileges (PR:H), there is no user interaction required (UI:N). The attack leads to a compromised of the confidentialy of the "super user" credentials of the device (VC:H/VI:N/VA:N), and can subsequently be used to full compromise and other devices (SC:H/SI:H/SA:H). Becuase this is an EV charger handing significant power, there is a potential safety impact (S:P). This attack can be automated (AU:Y).Show less

Tokens in CTFd used for account activation and password resetting can be used interchangeably for these operations. When used, they are sent to the server as a GET parameter and they are not single use, which means, that during token expiration time an on-path attacker might reuse such a token to change user's password and take over the account. Moreover, the tokens also include base64 encoded user email. This issue impacts releases up to 3.7.4 and was addressed by pull request 2679 https://github.com/CTFd/CTFd/pull/2679  included in 3.7.5 release.Show less

JUJU_CONTEXT_ID is a predictable authentication secret. On a Juju machine (non-Kubernetes) or Juju charm container (on Kubernetes), an unprivileged user in the same network namespace can connect to an abstract domain socket and guess the JUJU_CONTEXT_ID value. This gives the unprivileged user access to the same information and tools as the Juju charm.Show less
