This security bulletin contains information about 9 secuirty vulnerabilities.
1) Input validation error (CVE-ID: CVE-2021-22181)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input. A remote authenticated attacker can create a recursive pipeline relationship to exhaust resources and perform a denial of service (DoS) attack.
2) Cross-site scripting (CVE-ID: CVE-2021-22213)
The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.
The vulnerability exists due to insufficient sanitization of user-supplied data in the OAuth flow. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website.
Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.
3) Server-Side Request Forgery (SSRF) (CVE-ID: CVE-2021-22214)
The disclosed vulnerability allows a remote attacker to perform SSRF attacks.
The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can send a specially crafted HTTP request and trick the application to initiate requests to arbitrary systems.
Successful exploitation of this vulnerability may allow a remote attacker gain access to sensitive data, located in the local network or send malicious requests to other servers from the vulnerable system.
4) Resource exhaustion (CVE-ID: CVE-2021-22216)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources. A remote authenticated attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
5) Resource exhaustion (CVE-ID: CVE-2021-22217)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources. A remote authenticated attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
6) Improper Certificate Validation (CVE-ID: CVE-2021-22218)
The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to improper handling of x509 certificates. A remote authenticated attacker can spoof author of signed commits.
7) Information disclosure (CVE-ID: CVE-2021-22219)
The vulnerability allows a remote user to gain access to potentially sensitive information.
The vulnerability exists due to the sensitive information is not correctly registered for log masking. A remote administrator can gain unauthorized access to sensitive information on the system.
8) Stored cross-site scripting (CVE-ID: CVE-2021-22220)
The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.
The vulnerability exists due to insufficient sanitization of user-supplied data in blob viewer of notebooks. A remote attacker can inject and execute arbitrary HTML and script code in user's browser in context of vulnerable website.
Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.
9) Insufficient Session Expiration (CVE-ID: CVE-2021-22221)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to insufficient session expiration issue. A remote non-authenticated attacker can obtain or guess session token and gain unauthorized access to session that belongs to another user.
