Chegg, Inc.Breach6034/2020
Rankiteo Explanation :
Attack with significant impact with internal employee data leaks

Description: On April 27, 2020, the California Office of the Attorney General reported a data breach involving Chegg, Inc., which occurred on April 9, 2020. The breach potentially affected approximately 700 current and former U.S. Chegg employees, with compromised personal information including names and social security numbers.

Chegg, Inc.Breach8544/2018
Rankiteo Explanation :
Attack with significant impact with customers data leaks

Description: In September 2018, the California Office of the Attorney General disclosed a data breach affecting Chegg, Inc., an education technology company. The incident, discovered around April 29, 2018, involved an unauthorized party accessing a database containing sensitive user information. The compromised data included names, email addresses, shipping addresses, usernames, and hashed passwords. While no financial details (e.g., credit card numbers or bank statements) were reported as stolen, the exposure of personal and login credentials posed significant risks. Hashed passwords, though encrypted, could still be vulnerable to cracking attempts, potentially leading to unauthorized account access or credential stuffing attacks across other platforms where users reused passwords. The breach highlighted vulnerabilities in Chegg’s data security measures, raising concerns about user privacy and the potential for downstream fraud or identity theft. Customers were advised to reset passwords and monitor accounts for suspicious activity, though the long-term reputational and operational impacts on Chegg remained a concern.

Description

Nagios XI versions prior to 2026R1.1 are vulnerable to local privilege escalation due to an unsafe interaction between sudo permissions and application file permissions. A user‑accessible maintenance script may be executed as root via sudo and includes an application file that is writable by a lower‑privileged user. A local attacker with access to the application account can modify this file to introduce malicious code, which is then executed with elevated privileges when the script is run. Successful exploitation results in arbitrary code execution as the root user.

Description

SIPGO is a library for writing SIP services in the GO language. Starting in version 0.3.0 and prior to version 1.0.0-alpha-1, a nil pointer dereference vulnerability is in the SIPGO library's `NewResponseFromRequest` function that affects all normal SIP operations. The vulnerability allows remote attackers to crash any SIP application by sending a single malformed SIP request without a To header. The vulnerability occurs when SIP message parsing succeeds for a request missing the To header, but the response creation code assumes the To header exists without proper nil checks. This affects routine operations like call setup, authentication, and message handling - not just error cases. This vulnerability affects all SIP applications using the sipgo library, not just specific configurations or edge cases, as long as they make use of the `NewResponseFromRequest` function. Version 1.0.0-alpha-1 contains a patch for the issue.
