Most Affected Products
Yealink Meeting Server before V26.0.0.67 allows attackers to obtain static key information from a front-end JS file and decrypt the plaintext passwords based on the obtained key information.
Yealink Meeting Server before V26.0.0.67 is vulnerable to sensitive data exposure in the server response via sending HTTP request with enterprise ID.
Directory Traversal in the web interface of the Tiptel IP 286 with firmware version 2.61.13.10 allows attackers to overwrite arbitrary files on the phone via the Ringtone upload function.
An issue in Yealink VP59 Microsoft Teams Phone firmware 91.15.0.118 (fixed in 122.15.0.142) allows a physically proximate attacker to disable the phone lock via the Walkie Talkie menu option.
An issue discovered in Yealink VP59 Teams Editions with firmware version 91.15.0.118 allows a physically proximate attacker to gain control of an account via a flaw in the factory reset procedure.
Directory Traversal vulnerability in Yealink VP59 v.91.15.0.118 allows a physically proximate attacker to obtain sensitive information via terms of use function in the company portal component.
An issue was discovered in Yealink Configuration Encrypt Tool (AES version) and Yealink Configuration Encrypt Tool (RSA version before 1.2). There is a single hardcoded key (used to encrypt provisioning documents) across customers' installations.
Yealink Config Encrypt Tool add RSA before 1.2 has a built-in RSA key pair, and thus there is a risk of decryption by an adversary.
Yealink Meeting Server before v26.0.0.66 was discovered to contain an OS command injection vulnerability via the file upload interface.
An issue in YeaLinkSIP-T19P-E2 v.53.84.0.15 allows a remote privileged attacker to execute arbitrary code via a crafted request the ping function of the diagnostic component.
Directory Traversal vulnerability in Contacts File Upload Interface in Yealink W60B version 77.83.0.85, allows attackers to gain sensitive information and cause a denial of service (DoS).
Yealink Device Management (DM) 3.6.0.20 allows command injection as root via the /sm/api/v1/firewall/zone/services URI, without authentication.
The diagnostics web interface in the Yeahlink Ultra-elegant IP Phone SIP-T41P (firmware 66.83.0.35) does not validate (escape) the path information (path traversal), which allows an authenticated remote attacker to get access to privileged information (e.g., /etc/passwd) via path traversal (relative path information in the file parameter of the corresponding POST request).
A CSRF (Cross Site Request Forgery) in the web interface of the Yeahlink Ultra-elegant IP Phone SIP-T41P firmware version 66.83.0.35 allows a remote attacker to trigger code execution or settings modification on the device by providing a crafted link to the victim.
The network diagnostic function (ping) in the Yeahlink Ultra-elegant IP Phone SIP-T41P (firmware 66.83.0.35) allows a remote authenticated attacker to trigger OS commands or open a reverse shell via command injection.
Multiple cross-site scripting (XSS) vulnerabilities in Local Phone book and Blacklist form in Yealink VOIP Phones allow remote authenticated users to inject arbitrary web script or HTML via the user field to cgi-bin/ConfigManApp.com.
cgi-bin/cgiServer.exx in Yealink VoIP Phone SIP-T38G allows remote authenticated users to execute arbitrary commands by calling the system method in the body of a request, as demonstrated by running unauthorized services, changing directory permissions, and modifying files.
Absolute path traversal vulnerability in Yealink VoIP Phone SIP-T38G allows remote authenticated users to read arbitrary files via a full pathname in the dumpConfigFile function in the command parameter to cgi-bin/cgiServer.exx.
Directory traversal vulnerability in Yealink VoIP Phone SIP-T38G allows remote authenticated users to read arbitrary files via a .. (dot dot) in the page parameter to cgi-bin/cgiServer.exx.
CRLF injection vulnerability in Yealink VoIP Phones with firmware 28.72.0.2 allows remote attackers to inject arbitrary HTTP headers and conduct HTTP response splitting attacks via the model parameter to servlet.
config/.htpasswd in Yealink IP Phone SIP-T38G has a hardcoded password of (1) user (s7C9Cx.rLsWFA) for the user account, (2) admin (uoCbM.VEiKQto) for the admin account, and (3) var (jhl3iZAe./qXM) for the var account, which makes it easier for remote attackers to obtain access via unspecified vectors.
Cross-site scripting (XSS) vulnerability in Yealink VoIP Phones with firmware 28.72.0.2 allows remote attackers to inject arbitrary web script or HTML via the model parameter to servlet.
